Caution: risk of electric shock
Protective Conductor (*Earth) terminal
Functional/Protective Conductor (*Earth) terminal
Note: This symbol may also be used for a Protective Conductor
(Earth) Terminal if that terminal is part of a terminal block or
sub-assembly e.g. power supply.*NOTE: THE TERM EARTH USED THROUGHOUT THIS TECHNICAL MANUAL IS
THE DIRECT EQUIVALENT OF THE NORTH AMERICAN TERM GROUND.3.2 Labels
See Safety Guide (SFTY/4L M) for typical equipment labeling
information.4. INSTALLING, COMMISSIONING AND SERVICING
Equipment connections Personnel undertaking installation,
commissioning or servicing work on this equipment should be aware
of the correct working procedures to ensure safety. The equipment
documentation should be consulted before installing, commissioning,
or servicing the equipment. Terminals exposed during installation,
commissioning and maintenance may present a hazardous voltage
unless the equipment is electrically isolated. Any disassembly of
the equipment may expose parts at hazardous voltage, also
electronic parts may be damaged if suitable electrostatic voltage
discharge (ESD) precautions are not taken. If there is unlocked
access to the rear of the equipment, care should be taken by all
personnel to avoid electric shock or energy hazards. Voltage and
current connections should be made using insulated crimp
terminations to ensure that terminal block insulation requirements
are maintained for safety. Watchdog (self-monitoring) contacts are
provided in numerical relays to indicate the health of the device.
Schneider Electric Energy strongly recommends that these contacts
are hardwired into the substation’s automation system, for alarm
purposes. To ensure that wires are correctly terminated the correct
crimp terminal and tool for the wire size should be used. The
equipment must be connected in accordance with the appropriate
connection diagram. Protection Class I Equipment— Before energizing the equipment it must be earthed using the
protective conductor terminal, if provided, or the appropriate
termination of the -

supply plug in the case of plug connected equipment. — The
protective conductor (earth) connection must not be removed
sincethe protection against electric shock provided by the equipment
would be lost.— When the protective (earth) conductor terminal (PCT) is also
used to terminate cable screens, etc., it is essential that the
integrity of the protective (earth) conductor be checked after the
addition or removal of such functional earth connections. For M4
stud PCTs the integrity of the protective (earth) connections
should be ensured by use of a locknut or similar.The recommended minimum protective conductor (earth) wire size
is 2.5 mm (3.3 mm for North America) unless otherwise stated in the
technical data section of the equipment documentation, or otherwise
required by local or country wiring regulations. The protective
conductor (earth) connection must be low-inductance and as short as
possible. All connections to the equipment must have a defined
potential. Connections that are pre-wired, but not used, should
preferably be grounded when binary inputs and output relays are
isolated. When binary inputs and output relays are connected to
common potential, the pre-wired but unused connections should be
connected to the common potential of the grouped connections.
Before energizing the equipment, the following should be
checked:— Voltage rating/polarity (rating label/equipment
documentation); — CT circuit rating (rating label) and integrity of
connections; — Protective fuse rating; — Integrity of the
protective conductor (earth) connection (whereapplicable); — Voltage and current rating of external wiring,
applicable to the application.Accidental touching of exposed terminals If working in an area
of restricted space, such as a cubicle, where there is a risk of
electric shock due to accidental touching of terminals which do not
comply with IP20 rating, then a suitable protective barrier should
be provided.Equipment use If the equipment is used in a manner not specified
by the manufacturer, the protection provided by the equipment may
be impaired.Removal of the equipment front panel/cover Removal of the
equipment front panel/cover may expose hazardous live parts, which
must not be touched until the electrical power is removed.UL and CSA listed or recognized equipment To maintain UL and CSA
approvals the equipment should be installed using UL and/or CSA
listed or recognized parts of the following type: connection
cables, protective fuses/fuse holders or circuit breakers,
insulation crimp terminals, and replacement internal battery, as
specified in the equipment documentation.Equipment operating conditions The equipment should be operated
within the specified electrical and environmental limits. -
Safety Section

SS
Current transformer circuits Do not open the secondary circuit
of a live CT since the high voltage produced may be lethal to
personnel and could damage insulation. Generally, for safety, the
secondary of the line CT must be shorted before opening any
connections to it. For most equipment with ring-terminal
connections, the threaded terminal block for current transformer
termination has automatic CT shorting on removal of the module.
Therefore external shorting of the CTs may not be required, the
equipment documentation should be checked to see if this applies.
For equipment with pin-terminal connections, the threaded terminal
block for current transformer termination does NOT have automatic
CT shorting on removal of the module.External resistors, including voltage dependent resistors (VDRs)
Where external resistors, including voltage dependent resistors
(VDRs), are fitted to the equipment, these may present a risk of
electric shock or burns, if touched.Battery replacement Where internal batteries are fitted they
should be replaced with the recommended type and be installed with
the correct polarity to avoid possible damage to the equipment,
buildings and persons.Insulation and dielectric strength testing Insulation testing
may leave capacitors charged up to a hazardous voltage. At the end
of each part of the test, the voltage should be gradually reduced
to zero, to discharge capacitors, before the test leads are
disconnected.Insertion of modules and pcb cards Modules and PCB cards must
not be inserted into or withdrawn from the equipment whilst it is
energized, since this may result in damage.Insertion and withdrawal of extender cards Extender cards are
available for some equipment. If an extender card is used, this
should not be inserted or withdrawn from the equipment whilst it is
energized. This is to avoid possible shock or damage hazards.
Hazardous live voltages may be accessible on the extender card.External test blocks and test plugs Great care should be taken
when using external test blocks and test plugs such as the MMLG,
MMLB and MiCOM P990 types, hazardous voltages may be accessible
when using these. *CT shorting links must be in place before the
insertion or removal of MMLB test plugs, to avoid potentially
lethal voltages. *Note: When a MiCOM P992 Test Plug is inserted
into the MiCOM P991 Test Block, the secondaries of the line CTs are
automatically shorted, making them safe.Fiber-optic communication Where fiber-optic communication
devices are fitted, these should not be viewed directly. Optical
power meters should be used to determine the operation or signal
level of the device.Cleaning The equipment may be cleaned using a lint free cloth
dampened with clean water, when no connections are energized.
Contact fingers of test plugs are normally protected by petroleum
jelly, which should not be removed.Maintenance and installation For safety reason, no work must be
carried out on the P111Enh until all power sources to the unit have
been disconnected -

5. DE-COMMISSIONING AND DISPOSAL
De-commissioning The supply input (auxiliary) for the equipment
may include capacitors across the supply or to earth. To avoid
electric shock or energy hazards, after completely isolating the
supplies to the equipment (both poles of any dc supply), the
capacitors should be safely discharged via the external terminals
prior to de-commissioning.Disposal It is recommended that incineration and disposal to
water courses is avoided. The equipment should be disposed of in a
safe manner. Batteries should be removed from any equipment before
its disposal, taking precautions to avoid short circuits.
Particular regulations within the country of operation, may apply
to the disposal of the equipment.6. TECHNICAL SPECIFICATIONS FOR SAFETY Where UL Listing of the
equipment is not required the recommended fuse type is a high
rupture capacity (HRC) type with a maximum current rating of 16
Amps and a minimum DC rating of 250 Vdc, for example the Red Spot
NIT or TIA type.To maintain UL and CUL Listing of the equipment for North
America a UL Listed fuse shall be used. The UL Listed type shall be
a Class J time delay fuse, with a maximum current rating of 15 A
and a minimum DC rating of 250 Vdc, for example type AJT15.The protective fuse should be located as close to the unit as
possible.6.1 Protective fuse rating
DANGER — CTs must NOT be fused since open circuiting them may
produce lethal hazardous voltages.6.2 Protective class

Although the curves tend towards infinite when the current
approaches Is (general threshold), the minimum guaranteed value of
the operating current for all the curves with the inverse time
characteristic is 1.1 Is (with a tolerance of 0.05 Is).15.1.1 Inverse Time Curves
The first phase (or earth) overcurrent stage can be selected
with an inverse definite minimum time (IDMT) characteristic. The
time-delay is calculated using a mathematical formula.In all, there are eleven IDMT characteristics available.
The mathematical formula applicable to the first ten curves
is:+

RXIDG Curves
RXIDG curves can be selected on P111Enh Model E with wide earth
current (corresponding to Cortec model number P111xxx4xxxxxxxxxx
)The first earth thresholds can be selected with dedicated RXIDG
curves.The curves available follow the formula:
t = 5.8 1.35 * ln ( 1/ (k * Is/I))
Where:
t = tripping time
k = coefficient (from 0.3 to 1, by steps of 0.01)
Is = value of the programmed threshold (Pick-up value)
I = value of measured current
In order to be compliant with the Netmanagement specifications
the relay must be used with:An earth current range 0.01 Ion to 12 Ien
A rated current wiring 1A
A core balanced CT with a ratio 25/1.
15.1.2 Reset Timer
The first phase and earth overcurrent stages and the second
phase overcurrent stage are provided with a timer hold facility: «t
Reset».The value that is set for this reset timer corresponds to the
minimum time during which the current value needs to be lower than
95% of the phase (or earth) threshold before the corresponding
phase (or earth) time-delay is reset.Note: There is an exception to this rule when the protection
triggers. In fact, in that case, the time-delays (tI> and
tIe>) are immediately reset.The value of the Reset Timer depends on the type of timer
associated with the pick-up of the first phase (or earth)
stage.Type of timer associated with the first & second phase O/C

It may be set to a definite time value or to an inverse definite
minimum time characteristic (IEC/IEEE/ANSI curves only). This may
be useful in certain applications, for example when grading with
upstream electromechanical overcurrent relays that have inherent
reset time-delays.The second and third earth fault stages have only a definite
time reset.A possible situation where the reset timer may be used is to
reduce fault clearance times where intermittent faults occur.An example may occur in a cable with plastic insulation. In this
application it is possible that the fault energy melts the cable
insulation, which then reseals after clearance, thereby eliminating
the cause for the fault. This process repeats itself to give a
succession of fault current pulses, each of increasing duration
with reducing intervals between the pulses, until the fault becomes
permanent.When the reset time of the overcurrent relay is set to its
minimum, the relay will be repeatedly reset and will not be able to
trip until the fault becomes permanent. By using the reset timer
hold function the relay will integrate the fault current pulses,
thereby reducing the fault clearance time.The mathematical formula applicable to the five curves is:

3.1 Symbols
Caution: refer to equipment documentation
Caution: risk of electric shock
Protective Conductor (*Earth) terminal
Functional/Protective Conductor (*Earth) terminal
Note: This symbol may also be used for a Protective Conductor (Earth) Terminal if that terminal is part of a terminal block or sub-assembly e.g. power supply.
*NOTE: THE TERM EARTH USED THROUGHOUT THIS TECHNICAL MANUAL IS THE DIRECT EQUIVALENT OF THE NORTH AMERICAN TERM GROUND.
3.2 Labels
See Safety Guide (SFTY/4L M) for typical equipment labeling information.
4. INSTALLING, COMMISSIONING AND SERVICING
Equipment connections Personnel undertaking installation, commissioning or servicing work on this equipment should be aware of the correct working procedures to ensure safety. The equipment documentation should be consulted before installing, commissioning, or servicing the equipment. Terminals exposed during installation, commissioning and maintenance may present a hazardous voltage unless the equipment is electrically isolated. Any disassembly of the equipment may expose parts at hazardous voltage, also electronic parts may be damaged if suitable electrostatic voltage discharge (ESD) precautions are not taken. If there is unlocked access to the rear of the equipment, care should be taken by all personnel to avoid electric shock or energy hazards. Voltage and current connections should be made using insulated crimp terminations to ensure that terminal block insulation requirements are maintained for safety. Watchdog (self-monitoring) contacts are provided in numerical relays to indicate the health of the device. Schneider Electric Energy strongly recommends that these contacts are hardwired into the substation’s automation system, for alarm purposes. To ensure that wires are correctly terminated the correct crimp terminal and tool for the wire size should be used. The equipment must be connected in accordance with the appropriate connection diagram. Protection Class I Equipment
— Before energizing the equipment it must be earthed using the protective conductor terminal, if provided, or the appropriate termination of the
P111Enh/EN SS v1.3
Safety Section (SS) — 4
SS
supply plug in the case of plug connected equipment. — The protective conductor (earth) connection must not be removed since
the protection against electric shock provided by the equipment would be lost.
— When the protective (earth) conductor terminal (PCT) is also used to terminate cable screens, etc., it is essential that the integrity of the protective (earth) conductor be checked after the addition or removal of such functional earth connections. For M4 stud PCTs the integrity of the protective (earth) connections should be ensured by use of a locknut or similar.
The recommended minimum protective conductor (earth) wire size is 2.5 mm² (3.3 mm² for North America) unless otherwise stated in the technical data section of the equipment documentation, or otherwise required by local or country wiring regulations. The protective conductor (earth) connection must be low-inductance and as short as possible. All connections to the equipment must have a defined potential. Connections that are pre-wired, but not used, should preferably be grounded when binary inputs and output relays are isolated. When binary inputs and output relays are connected to common potential, the pre-wired but unused connections should be connected to the common potential of the grouped connections. Before energizing the equipment, the following should be checked:
— Voltage rating/polarity (rating label/equipment documentation); — CT circuit rating (rating label) and integrity of connections; — Protective fuse rating; — Integrity of the protective conductor (earth) connection (where
applicable); — Voltage and current rating of external wiring, applicable to the application.
Accidental touching of exposed terminals If working in an area of restricted space, such as a cubicle, where there is a risk of electric shock due to accidental touching of terminals which do not comply with IP20 rating, then a suitable protective barrier should be provided.
Equipment use If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Removal of the equipment front panel/cover Removal of the equipment front panel/cover may expose hazardous live parts, which must not be touched until the electrical power is removed.
UL and CSA listed or recognized equipment To maintain UL and CSA approvals the equipment should be installed using UL and/or CSA listed or recognized parts of the following type: connection cables, protective fuses/fuse holders or circuit breakers, insulation crimp terminals, and replacement internal battery, as specified in the equipment documentation.
Equipment operating conditions The equipment should be operated within the specified electrical and environmental limits.
Safety Section
P111Enh/EN SS v1.3 (SS) — 5
SS
Current transformer circuits Do not open the secondary circuit of a live CT since the high voltage produced may be lethal to personnel and could damage insulation. Generally, for safety, the secondary of the line CT must be shorted before opening any connections to it. For most equipment with ring-terminal connections, the threaded terminal block for current transformer termination has automatic CT shorting on removal of the module. Therefore external shorting of the CTs may not be required, the equipment documentation should be checked to see if this applies. For equipment with pin-terminal connections, the threaded terminal block for current transformer termination does NOT have automatic CT shorting on removal of the module.
External resistors, including voltage dependent resistors (VDRs) Where external resistors, including voltage dependent resistors (VDRs), are fitted to the equipment, these may present a risk of electric shock or burns, if touched.
Battery replacement Where internal batteries are fitted they should be replaced with the recommended type and be installed with the correct polarity to avoid possible damage to the equipment, buildings and persons.
Insulation and dielectric strength testing Insulation testing may leave capacitors charged up to a hazardous voltage. At the end of each part of the test, the voltage should be gradually reduced to zero, to discharge capacitors, before the test leads are disconnected.
Insertion of modules and pcb cards Modules and PCB cards must not be inserted into or withdrawn from the equipment whilst it is energized, since this may result in damage.
Insertion and withdrawal of extender cards Extender cards are available for some equipment. If an extender card is used, this should not be inserted or withdrawn from the equipment whilst it is energized. This is to avoid possible shock or damage hazards. Hazardous live voltages may be accessible on the extender card.
External test blocks and test plugs Great care should be taken when using external test blocks and test plugs such as the MMLG, MMLB and MiCOM P990 types, hazardous voltages may be accessible when using these. *CT shorting links must be in place before the insertion or removal of MMLB test plugs, to avoid potentially lethal voltages. *Note: When a MiCOM P992 Test Plug is inserted into the MiCOM P991 Test Block, the secondaries of the line CTs are automatically shorted, making them safe.
Fiber-optic communication Where fiber-optic communication devices are fitted, these should not be viewed directly. Optical power meters should be used to determine the operation or signal level of the device.
Cleaning The equipment may be cleaned using a lint free cloth dampened with clean water, when no connections are energized. Contact fingers of test plugs are normally protected by petroleum jelly, which should not be removed.
Maintenance and installation For safety reason, no work must be carried out on the P111Enh until all power sources to the unit have been disconnected
P111Enh/EN SS v1.3

5. DE-COMMISSIONING AND DISPOSAL
De-commissioning The supply input (auxiliary) for the equipment may include capacitors across the supply or to earth. To avoid electric shock or energy hazards, after completely isolating the supplies to the equipment (both poles of any dc supply), the capacitors should be safely discharged via the external terminals prior to de-commissioning.
Disposal It is recommended that incineration and disposal to water courses is avoided. The equipment should be disposed of in a safe manner. Batteries should be removed from any equipment before its disposal, taking precautions to avoid short circuits. Particular regulations within the country of operation, may apply to the disposal of the equipment.
6. TECHNICAL SPECIFICATIONS FOR SAFETY Where UL Listing of the equipment is not required the recommended fuse type is a high rupture capacity (HRC) type with a maximum current rating of 16 Amps and a minimum DC rating of 250 Vdc, for example the Red Spot NIT or TIA type.
To maintain UL and CUL Listing of the equipment for North America a UL Listed fuse shall be used. The UL Listed type shall be a Class J time delay fuse, with a maximum current rating of 15 A and a minimum DC rating of 250 Vdc, for example type AJT15.
The protective fuse should be located as close to the unit as possible.
6.1 Protective fuse rating
DANGER — CTs must NOT be fused since open circuiting them may produce lethal hazardous voltages.
6.2 Protective class
IEC 60255-27: 2005 Class I (unless otherwise specified in the equipment documentation). .

15. CURVES 15.1 General
Although the curves tend towards infinite when the current approaches Is (general threshold), the minimum guaranteed value of the operating current for all the curves with the inverse time characteristic is 1.1 Is (with a tolerance of ± 0.05 Is).
15.1.1 Inverse Time Curves
The first phase (or earth) overcurrent stage can be selected with an inverse definite minimum time (IDMT) characteristic. The time-delay is calculated using a mathematical formula.
In all, there are eleven IDMT characteristics available.
The mathematical formula applicable to the first ten curves is:

RXIDG Curves
RXIDG curves can be selected on P111Enh Model E with wide earth current (corresponding to Cortec model number P111xxx4xxxxxxxxxx )
The first earth thresholds can be selected with dedicated RXIDG curves.
The curves available follow the formula:
t = 5.8 – 1.35 * ln ( 1/ (k * Is/I))
Where:
t = tripping time
k = coefficient (from 0.3 to 1, by steps of 0.01)
Is = value of the programmed threshold (Pick-up value)
I = value of measured current
In order to be compliant with the Netmanagement specifications the relay must be used with:
• An earth current range 0.01 Ion to 12 Ien
• A rated current wiring 1A
• A core balanced CT with a ratio 25/1.
15.1.2 Reset Timer
The first phase and earth overcurrent stages and the second phase overcurrent stage are provided with a timer hold facility: «t Reset».
The value that is set for this reset timer corresponds to the minimum time during which the current value needs to be lower than 95% of the phase (or earth) threshold before the corresponding phase (or earth) time-delay is reset.
Note: There is an exception to this rule when the protection triggers. In fact, in that case, the time-delays (tI> and tIe>) are immediately reset.
The value of the Reset Timer depends on the type of timer associated with the pick-up of the first phase (or earth) stage.

It may be set to a definite time value or to an inverse definite minimum time characteristic (IEC/IEEE/ANSI curves only). This may be useful in certain applications, for example when grading with upstream electromechanical overcurrent relays that have inherent reset time-delays.
The second and third earth fault stages have only a definite time reset.
A possible situation where the reset timer may be used is to reduce fault clearance times where intermittent faults occur.
An example may occur in a cable with plastic insulation. In this application it is possible that the fault energy melts the cable insulation, which then reseals after clearance, thereby eliminating the cause for the fault. This process repeats itself to give a succession of fault current pulses, each of increasing duration with reducing intervals between the pulses, until the fault becomes permanent.
When the reset time of the overcurrent relay is set to its minimum, the relay will be repeatedly reset and will not be able to trip until the fault becomes permanent. By using the reset timer hold function the relay will integrate the fault current pulses, thereby reducing the fault clearance time.
The mathematical formula applicable to the five curves is:

IP = Steady state pre-loading current before application of the overload
The tripping time varies depending on the load current carried before application of the overload, i.e. whether the overload was applied from «hot» or «cold».
The thermal overload time characteristic curves are given in the Technical Data chapter.

BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE SAFETY GUIDE SFTY/4L M/E11 OR LATER ISSUE, OR THE SAFETY AND TECHNICAL DATA SECTION OF THE TECHNICAL MANUAL AND ALSO THE RATINGS ON THE EQUIPMENT RATING LABEL.
For safety reasons, no work must be carried out on the P111 until all power sources to the unit have been disconnected.
1. RELAY POWER UP Follow the following instructions carefully in order to correctly power up the relay.
1.1 System Connections
Check the wiring scheme of your installation.
Check that the output relay contacts are included in your trip circuit.
1.2 Auxiliary Power Supply Connections
Connect a DC or AC (according to nominal supply rating VAUX) voltage power supply.
Positive VAUX to terminal A1 Negative VAUX to terminal A2
Turn on the auxiliary power supply and set to approximately the rated voltage as shown on the relay’s front panel.
The display should show:
1.00 A 1.00 A
1.00 A 1.00 A
Displays: — first line: phases A and B currents, — second line: phase C current and earth current, taking into account the phase CT ratio (CONFIGURATION/CT RATIO submenu).
The LEDs should be configured as follows:
− The green LED «Healthy» (watchdog) is illuminated
The configuration of the remaining LEDs depends on the relay’s history before powering (if the LEDs are configured as latching their state is stored in memory, therefore after repowering they are illuminated again until they are manually reset).
1.3 Powering up from the USB port (function not available in Model N)
Only some of the relay’s electronic circuits, for the HMI and RS485 communications, are supplied from the USB port.
Note: Since the I/O boards are not supplied from the USB port the inputs’ status is set to default value. Additionally, output contacts are not operational therefore it is impossible to execute any commands.

Figure 2: Rear View of the P111
2.2 Relay connection and power-up
The relay can be powered from the following sources:
— Auxiliary voltage Vaux (terminals A1-A2)
— USB port (only some electronic boards: to ensure HMI, USB and/or RS485 communications)
Note:
1. USB is not available in model L
2. USB not supply electronic of P111Enh in model N. The auxiliary voltage have to present on A1-A2 terminals
2.2.1 Auxiliary Supply Voltage (Vaux) connection
Before applying the auxiliary supply voltage to the relay, check that the rated nominal ac or dc voltage is appropriate for the application and that it will be connected to the correct terminals (A1&A2). The relay’s serial number, current rating, and power rating information can be viewed on the upper side of the case. The ac or dc supply voltage must be within the corresponding nominal range of the device, as indicated in the table below, for the appropriate nominal rating of the equipment:
Model Nominal ranges of auxiliary voltage Vaux Operative dc range Operative ac range
ABE 24 to 60 Vac/dc 19 to 72 Vdc 19 to 66 Vac
ABE 90 to 250 Vdc and 90 to 240 Vac 71 to 300 Vdc 71 to 265 Vac
LN 24 to 250 Vdc and 24 to 240 Vac 19 to 300 Vdc 19 to 265 Vac
Once the ratings have been verified for the application, connect the equipment to an external power source capable of delivering the requirements specified on the label, to perform the relay familiarization procedures. Please refer to the wiring diagrams in the Installation section for complete installation details, ensuring that the correct polarities are observed in the case of dc supply.
Note: The label specifies the auxiliary voltage for the P111 supply input and binary inputs (dependent on ordering options).
2.2.2 Current inputs
The measuring current inputs of the P111 should be connected to the secondary wires of the power system CTs as shown in the connection diagrams in section 8 of P111 Installation chapter P111Enh/EN IN.
The parameters of the CTs that can be connected to the P111’s current input terminals are detailed in section 3 of chapter P111Enh/EN AP — Applications.

The input connection diagram is shown in section 8 of chapter P111Enh/EN IN — Installation.
2.3 Introduction to the user interfaces and setting options
The relay has a USB user interface for use with MiCOM S1 OR S1 STUDIO software.
P111Enh/EN GS v1.3
Getting Started (GS) 3-12 MiCOM P111Enh
GS
With this interface it is possible to download the setting values, latest fault, alarm and instantaneous records (E) as well as disturbance records (AE) and fully configure the P111.
Note: After connection to the USB port the Healthy LED is lit. If the LED is not lit refer to chapter P111Enh/EN TS — Troubleshooting.
The USB port integrates electronic boards only to allow communications with the P111 via the HMI/RS485/USB interfaces.
2.4 Changing parameters via the front panel user interface (HMI)
Changing of all parameters is password-protected.
After restart or powering up, the P111Enh is in Protection Mode. This means that all settings are the same as in the relay’s operation system and are available on the front panel user interface.
To change any parameters, it is necessary to switch the P111Enh to the SETTING CHANGE MODE.
The SETTING CHANGE MODE, for entered password level which changes setting parameters, is indicated by the sequential flashing of the programmable LEDs (from 4 up to 8 LEDs) on the front panel.
Until it is switched back from the SETTING CHANGE MODE to the PROTECTION MODE, or restarted by disconnecting then reconnecting the power supply, the P111Enh uses the setting parameters that were active before the SETTING CHANGE MODE was entered (previous settings).
Press the OK navigation key, after changing a chosen parameter (confirmation of change). The new value is saved in FRAM memory but the P111ENH still uses the setting value that was active before the SETTING CHANGE MODE was entered (previous settings). The new value will be available in the operation system only after the firmware has been reset. When the firmware is reset, all the settings are loaded into the P111ENH system.
When switching from the SETTING CHANGE MODE to the PROTECTION MODE, a warm reset is applied.
The P111Enh therefore applies the new parameters to the relay’s operation system.
Afterwards, the settings available on the front panel and those used by the operation system are consistent.
Note: While the LEDs are flashing (SETTING CHANGE MODE by entering Administrator or Protection setting password) there can be a mismatch between the settings displayed on the front panel and those used by the operating system.
When “Control only” rights password is entered there is no any LED signaling like for Administrator or Protection setting password. Additionally all changes are executed and recorded immediately (no need warm reset of firmware). Because this level is not signaled so after 10 minutes P111ENH switches back automatically from the SETTING CHANGE MODE to the PROTECTION MODE.
The password protection of the relay comprises three levels:
− Administrator (Without limits)
− Protection setting (Protection only)
− Control only (Test control) – this level is used for tests and/or control execution only (no changing of setting parameters) so signaling of SETTING CHANGE MODE differs from above. On this password level there is no the sequential flashing of the programmable LEDs (from 4 up to 8 LEDs). On the control windows is the special sign: which informs that control is allowed.
Administrator rights: all the menu settings may be changed (violet color on Fig.10-21).
Getting Started
P111Enh/EN GS v1.3
MiCOM P111Enh (GS) 3-13
GS
Protection setting rights: it is possible to change settings in the PROTECTION column; CTRL Default Windows (CB status CTRL, L/R status CTRL, [79] CTRL ) and COMMISSIONING/Maintenance Mode windows are also possible (green color on Fig.10-21).
Control rights: CTRL Default Windows (CB status CTRL, L/R status CTRL, [79] CTRL ) and COMMISSIONING/Maintenance Mode windows from the front panel only (yellow color on Fig.10-21).
For each level the password consists of 4 digits (0 to 9)
NOTE: The default password is 0000 for every password protection level.
It is recommended to change default password from 0000 to unique value for every password level.
If the first password is different, this means that the Administrator password has been changed.
The Protection setting password is still 0000. Therefore, to protect settings against unauthorized access it is necessary to change the Protection setting password by first entering 0000 then a new value.
The Control password is still 0000. Therefore, if it is necessary to change it, first enter 0000 then the new value (Control right) of the password.
Notes: 1. If the Protection setting rights have not been changed, or if it has been set to the default value (0000), it is possible to change all the settings in the PROTECTION column, reset the counters and control the CB without entering a password, simply by pressing the OK navigation key. This makes it possible to change a chosen parameter by automatically switching the P111ENH to the SETTING CHANGE MODE (the programmable LEDs are flashing). This means that even after changing only one parameter it is necessary to switch the P111ENH back to PROTECTION MODE in order to activate the new settings (warm restart).
2. If the Control rights password has not been changed or if it has been set to the default value (0000) it is possible to control the CB in menu without password protection.
2.4.1 SETTING CHANGE MODE
The SETTING CHANGE MODE should be used to change settings.
Using the SETTING CHANGE MODE ensures that all changed parameters will be applied simultaneously so as to avoid any problems caused by possible setting inconsistencies.
The SETTING CHANGE MODE makes it possible to change settings while the relay is active without any risk (the P111Enh continues to use the previous settings).
After exiting the SETTING CHANGE MODE a warm reset of firmware is applied so that all the protection counters are reset.
Note: Latched LEDs and outputs are not reset (stored values are not cleared during a P111Enh reset)
To switch the P111Enh to the SETTING CHANGE MODE navigate to the SETTING CHANGE MODE main header (see Figure 9), then press the key:
Edit settings? Enter PSWD
Press the OK navigation key.

2.5.2 ALARM STATUS column
ALARM STATUS (see Figure 4) information is available if the cause of alarm has been triggered. Therefore, if after pressing the key no the new cell is displayed, it means that no alarms have been detected.
Depending on the P111’s configuration an alarm signal is self-resetting (no cause of alarm – no alarm signal; GLOBAL SETTINGS/LOC/Alarm Display 0: Self-reset) or manually resettable (alarm signal latched; GLOBAL SETTINGS/LOC/Alarm Display 1: Latching).
Default setting: 0: Self-Reset. This means that if an alarm signal has disappeared no information is available in the ALARM STATUS column.
If set to Latching, this means that if an alarm signal has disappeared information is still available in the ALARM STATUS column until it is reset in the ALARM STATUS/ Alarm Reset window.
Alarm information is always available in the event recorder. However, the programmable LEDs can be used to store causes of alarm if required.
Figure 4 shows all causes of alarms (if alarms have been enabled in the main configuration column of the protection function).

− Test outputs – if set to 1: apply test, pressing the OK navigation key will execute the test of the outputs (AE),
− Functional Test – allows the user to set the protection criteria to be tested (AE),
− Functional Test End – defines the end of the functional test: CB opened or Time (AE),

It is possible to set following Maintenance mode options (AE) :
• “No” — Maintenance mode is disabled. All window cells below are hidden (Maintenance mode is the latest cell in COMMISIONING column)
• “Yes,outp.trips” — Maintenance mode is enabled. In this mode all test cells in COMMISIONING column are available (see Fig.8 below). During tests outputs are energized.
• “Yes,outp.block” — Maintenance mode is enabled and all test cells in COMMISIONING column are available (see Fig.8 below). In this mode, the high state of output functions are ignored (control of outputs are blocked).
This operation requires entering a Control rights password (Test control).
It is possible to set additional programmable LED for Maintenance Mode.
Note: The Maintenance Mode is active up to 10 minutes only. After this time P111Enh automatically sets — Maintenance mode: “No”. It protects user against leaving the P111Enh in this mode after tests.

3. LOCAL CONNECTION MiCOM P11x TO A PC 3.1 Configuration
Local connection between a PC and the relay is made through a USB cable.
Before connection cable to USB socket it is necessary discharge static electricity from the body by touching a metal grounded object (such as an unpainted metal surface) to prevent against ESD damage
Before communications can be established between a PC and a device fitted with a USB port, the device’s Windows driver must first be installed and a virtual COM port created.
The latest MiCOM S1 STUDIO software has a built-in USB driver and virtual COM software, but if an older version of S1 STUDIO or MiCOM S1 are used it will be necessary to install the above in order to have communication facilities.
If the PC is connected both to the Internet and to the device, the USB driver and virtual COM software can be downloaded via Windows automatically from the web. Depending on firewall configuration, this may however not always be possible.
In such a case it is necessary to install the P11x USB driver and virtual COM software manually.
3.2 USB Driver and virtual COM software installation
Two installation methods are available:
− Automatic installation using an Internet connection (installation files are not needed in this case),
− Setup file («Setup P11x USB driver CDM 2.xx.xx.exe») which can be delivered via an Schneider Electric contact or downloaded from Schneider Electric website.
Note: The latest S1 STUDIO software includes all drivers therefore no action is needed.

3.4 MiCOM S1 and MiCOM S1 Studio relay communications basics
MiCOM S1 and MiCOM S1 Studio are the universal MiCOM IED Support Software packages which provide users with a direct and convenient access to all data stored in any MiCOM IED using the USB front communication port.
MiCOM S1 and MiCOM S1 Studio provide full access to:
− MiCOM Px10 Px20, Px20, Px30, Px40 relays
− MiCOM Mx20 measurements units
The following sections give the main procedures to connect to and to use MiCOM S1 and MiCOM S1 Studio.
Before starting, check that the USB serial cable is properly connected to the USB port on the front panel of the relay. Please follow the instructions given in section 3.1 in order to ensure proper connection between the PC and the relay before attempting to communicate with the relay.
This section is intended as a quick start guide to using MiCOM S1 and MiCOM S1 Studio, and assumes that you have a copy of MiCOM S1 or MiCOM S1 Studio installed on your PC. Please refer to the MiCOM S1 or MiCOM S1 Studio User Manual for more detailed information.

1. GENERAL INFORMATION The P111 must be configured to the system and application by means of the appropriate settings. This section gives instructions for determining the settings, which are located in the folder entitled, Schneider Electric Energy in the menu tree. The order in which the settings are listed and described in this chapter is: the protection settings, control and configuration settings (see section P111/EN GS for the detailed relay menu map). The relay is supplied with a factory-set configuration of default settings
All current settings refer to nominal current (for NBE setting value, for L ordering option: 1 A or 5 A). The nominal current can be defined separately for phase (In) and earth (Ien) currents in the ordering process (ordering hardware option).
MiCOM S1 can be used to download and upload protection and configuration setting values via the relay’s USB port.
The protection and I/O settings include all the following items that become active once enabled in the configuration column of the relay menu database:
− Protection element settings.
− Output settings
− Input settings
− LED settings
There are two groups of protection and I/O settings, with each group containing the same setting cells. One group of protection and I/O settings is selected as the active group, and is used by the protection elements. The settings for group 1 are shown. The settings are discussed in the same order in which they are displayed in the menu.

2. SETTINGS 2.1 Protection Settings
2.1.1 Phase O/C [50/51]
The overcurrent protection included in the P111 relay provides non-directional three-phase overcurrent protection with independent time-delay characteristics. All overcurrent settings apply to all of the three phases but are independent for each of the three stages.
The first two overcurrent stages have time-delayed characteristics which are selectable between inverse definite minimum time (IDMT) and definite time (DMT). The third stage has definite time characteristics (DMT) only.

I> ? Disabled Disabled, Trip, Alarm, Trip-Inrush Bl (AE), Trip-Latch (AE), Trip-Phase A (E), Trip-Phase B (E), Trip-Phase C (E)
Setting to disable or enable the protection element. The protection element can be set to trip the CB (Enable Trip), only issue an Alarm signal (Enable Alarm), trip the CB with Inrush Blocking logic (Trip-Inrush Bl) or trip the CB with latching until reset (Trip-Latch). If the protection element is set to ‘Trip’ or ‘Trip-Inrush Bl’ or ‘Trip-Latch’ it means that it is linked to the Protection trip (see LED and Output configuration) and Trip Command (see Output configuration) functions. Additionally this protection element will trigger fault recording, disturbance recording, as well as the Trip LED on the front panel. If the protection element is set to ‘Alarm’ it means that it is linked to the Alarm function (see LED and Output configuration) and ‘ALARM STATUS’ indication..

2.1.2 SOTF (Switch On To Fault function) (ABE)
With the Switch On To Fault (SOTF) submenu, it is possible to shorten the time to trip when for example the relay has detected a fault that is still present on a feeder after energizing.
The SOTF overcurrent element is activated after the CB’s state changes from open to closed. SOTF is blocked when the auto-recloser is running (E).
SOTF? Disabled Disabled, Trip, Alarm, Trip-Inrush Bl (AE), Trip-Latch (AE),
Setting to disable or enable the protection element. The protection element can be set to trip the CB (Enable Trip), only issue an Alarm signal (Enable Alarm), trip the CB with Inrush Blocking logic (Trip-Inrush Bl) or trip the CB with latching until reset (Trip-Latch). If the protection element is set to ‘Trip’ or ‘Trip-Inrush Bl’ or ‘Trip-Latch’ it means that it is linked to the Protection trip (see LED and Output configuration) and Trip Command (see Output configuration) functions. Additionally this protection element will trigger fault recording, disturbance recording, as well as the Trip LED on the front panel. If the protection element is set to ‘Alarm’ it means that it is linked to the Alarm function (see LED and Output configuration) and ‘ALARM STATUS’ indication.

2.1.3 E/Gnd Fault [50N/51N]
The earth fault element operates from earth fault current that is measured directly from the system; either by means of a separate CT located in a power system earth connection or via a residual connection of the three line CTs.
All overcurrent settings are independent for each of the two stages (Model E: three stages).
The first stage of e/f non-directional overcurrent protection has time-delayed characteristics which are selectable between inverse definite minimum time (IDMT) and definite time (DMT). The second stage and the third (E) have definite time characteristics only.

2.1.7 CB Fail [50BF]
This function consists of a circuit breaker fail function that can be initiated by:
Current based protection elements
External protection element (AE): Strt tBF function (SETTING GROUP x/INPUTS/ column).
For current-based protection, the reset condition is based on undercurrent operation to determine whether the CB has opened.
It is common practice to use low set undercurrent elements in protection relays to indicate that circuit breaker poles have interrupted the fault or load current, as required.
If an external protection is set to trigger the CB Fail element, the trip input must also be mapped to the Strt tBF function (AE). The resetting of the tBF timer is based on the I< Threshold CBF and IN< Threshold CBF criteria only. Therefore if an external protection issues a latched trip signal but currents fall below the undercurrent thresholds, CB Fail will not issue the CB Fail signal.

Setting to disable or enable the AUX element. The element can be set to:
— trip the CB (Enable Trip), — signal only (Alarm), — trip the CB with Inrush Blocking logic (Trip-Inrush Bl) — trip the CB with latching until reset (Trip-Latch) — trip the CB when a binary input receives the information that the frequency of
power system is too low (Load Shedding). This information is saved as long as the CB remains open or until the power system’s frequency returns to its nominal value. The above information is based on the status of the binary input mapped to AUX (SETTING GROUP x/INPUT CONFIGURATION Gx/AUX) with AUX set to AR after LS Hi or to AR after LS Lo (tripping occurs upon expiry of the tAUX time-delay). The trip command is sent via the Trip CB order output (SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx/Trip CB order).
— reclose after Load Shedding triggered by a high state of the AUX function (AR after LS Hi). Load shedding information is based on the status of the binary input mapped to AUX (SETTING GROUP x/INPUT CONFIGURATION Gx/AUX) with AUX set to Load Shedding. If the P111Enh has saved Load Shedding information and AUX indicates that the power system frequency has returned to its nominal value, the tAUX time-delay is started. At the end of tAUX the close command is issued. The close command is issued via the Close CB order output (SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx/Close CB order).

Setting to Disable or Current+Input or Input only the Cold Load PU element. This function increases or decreases the thresholds for Cold Load PU level via tCL pulse time. Input only: tCL is started by a binary input assigned to the Cold PU function. For example: Typically increasing of the threshold is applied when the CB changes position from 52b to 52a (closing CB), therefore the input mapped to CB status 52a should be assigned to the Cold PU function too. Current+Input: tCL is started by a binary input assigned to the Cold PU function (as above) or based on the current stages: 5%In and 10%In. If the current in all phases are below 5%In by over 10s, after increasing of current above 10%In at least in a one phase tCL is started.

2.1.11 Auto-reclose [79] (E)
The auto-reclose function provides the ability to automatically control the recloser, with one, two, three, or four shot cycles. Each cycle implements a dead time and a reclaim time.
During the auto-reclosing cycle, if the relay receives a command to switch setting groups, this command is kept in memory, and will be executed only after the timer elapses.
The auto-reclose function is available if:
• a logical input is assigned to the 52a state (if the CB trips option is set in submenu: GLOBAL SETTINGS/[79] ADVANCED SETTINGS/Start Dead t on), • and the trip output relay is not latched to the earth and/or phase protection element.
In addition to these settings, the user can fully link the auto-reclose function to the protection function using the menus PROTECTION G1 / Phase OC and PROTECTION G1/ E/Gnd.

Fast O/C Trip 00000 0-1 1
This function allows faster tripping by phase overcurrent criteria when the auto-recloser is running. The Fast Trip function increases the number of successful auto-reclosures. The best result is obtained with fast tripping set to 0 s (instantaneous trip), but because of transient currents it is sometimes necessary to set a value greater than 0 s in order to avoid maloperation. If bit “1” is set, the value for Fast O/C Trip Delay is used instead of the protection element’s time-delay Note: If the protection element’s time-delay is shorter than the Fast Trip’s time-delay, tripping occurs upon expiry of the protection element’s time-delay (the shortest timer is used).

Latched Outputs 0000000 0-1 1
Each output can be configured with or without latching. Default Setting: “00000” means that: RL7: “0” – output RL5 is not latched. The high state of the function mapped to the output
determines the high state of RL7. The low state of this function determines the low state of RL7 (A).
RL6: “0” – see RL7 (A). RL5: “0” – see RL7 (NEA). RL4: “0” – see RL7 (NEA). RL3: “0” – see RL7 (LBNEA). RL2: “0” – see RL7 (LBNEA). RL1: “0” – see RL7 (LBNEA). The high state of the function mapped to the output determines the high state of
the output relay. The low state of this function does not change the state of the output relay. For the low state of output relay, it is necessary to activate the Reset of Latched Output function (via a binary input, from the front panel or via a communication port)

3.5 Inrush Blocking (AE)
The 2nd Harmonic Blocking detects high inrush current flows that occur when transformers or machines are connected. The function will then block the following functions:
o PHASE O/C [50/51]
o SOTF [50/51] (BAE)
o E/GND FAULT [50/51N]
o NEGATIVE SEQ. O/C [46] (E)
o BROKEN CONDUCTOR (E)
o AUX TIMERS (BAE)
Blocking of a protection function is enabled if the main configuration of protection criteria is set to “Trip-Inrush Bl” (for example: “SETTING GROUP x/PROTECTION Gx/PHASE O/C [50/51] Gx/I>? Trip-Inrush Bl” submenu)
The 2nd Harmonic Blocking function identifies an inrush current by evaluating the ratio of the second harmonic current components to the fundamental wave. If this ratio exceeds the set thresholds, then the inrush stabilization function operates.
The minimum fundamental current value required for operation of the Inrush Blocking function is 0.2 In, and there is no upper limit to disable this feature.
2nd Harmonic Blocking operates across all phases.

Note: Typically the Reset Time should be set to 0 ms, because second harmonic blocking can cause an additional tripping delay. If unwanted tripping can be caused by the inrush phenomena this value can be increased. This setting is available when Inrush Blocking? Is set to Yes or Closing
Unblock Inrush Time 1 s 0.0 s 200 s 0.01 s

1. OPERATION OF INDIVIDUAL PROTECTION FUNCTIONS The following sections detail the individual protection functions.
1.1 Overcurrent Protection
The overcurrent protection included in the P111Enh relays provides three-stage non-directional three-phase overcurrent protection with independent time-delay characteristics. All overcurrent settings apply to all three phases but are independent for each of the three stages.
Each protection stage can be selected to Trip the CB or to issue a signal (Alarm) only.
If an overcurrent protection stage (I>?, I>>? or I>>>? menu) is set to Trip, Trip-Inrush Bl, Trip-Latch, Trip-Phase A (E), Trip-Phase B (E) or Trip-Phase C (E) it means that that stage is linked to the Protect.Trip and Prot.Trip pulse functions (see LED and Output configuration).
If an overcurrent protection stage (I>?, I>>? or I>>>? menu) is set to Alarm, it means that that stage is linked to the Alarm function (see LED and Output configuration).
If Trip-Inrush Bl is selected, the overcurrent stage is blocked via the Inrush Blocking function (refer to Inrush Blocking section).
If Trip-Latch is selected, the overcurrent stage will remain high after a trip, until it is reset via a binary input, the HMI or a remote RESET command.
If Trip-Phase A is selected, the overcurrent stage is compared with the current in phase A only (tripping is based on phase A measurement only; the rest phases: B and C are ignored).
If Trip-Phase B is selected, the overcurrent stage is compared with the current in phase B only (tripping is based on phase B measurement only, the rest phases: A and C are ignored).
If Trip-Phase C is selected, the overcurrent stage is compared with the current in phase C only (tripping is based on phase C measurement only, the rest phases: A and B are ignored).

1.1.1 Operation Time-Delay
The first (I>) and second (I>>) stages of overcurrent protection have time-delayed characteristics which are selectable between inverse definite minimum time (IDMT) and definite time (DMT). The third (I>>>) stage has a definite time characteristic only.
Various methods are available to achieve correct relay co-ordination on a system; by means of time alone, current alone or a combination of both time and current. Grading by means of current is only possible where there is an appreciable difference in fault level between the two relay locations. Grading by time is used by some utilities but can often lead to excessive fault clearance times at or near source substations where the fault level is highest. For these reasons the most commonly applied characteristic in coordinating overcurrent relays is the IDMT type.
The inverse time-delayed characteristics indicated above comply with the following formulae:

RXIDG Curves
RXIDG curves can be selected on P111Enh with medium earth current sensitivity (corresponding to Cortec model number P111Exxx4xxxxxxxxxx)
The first earth thresholds can be selected with dedicated RXIDG curves.
The curves available follow the formula:
t = 5.8 – 1.35 * ln ( 1/ (k * Is/I))
Where:
t = tripping time
k = coefficient (from 0.3 to 1, by steps of 0.01)
Is = value of the programmed threshold (Pick-up value)
I = value of measured current
In order to be compliant with the Netmanagement specifications the relay must be used with:
• An earth current range 0.01 Ion to 12 Ion
• A rated current wiring 1A
• A core balanced CT with a ratio 25/1.

1.1.2 Timer Hold Facility
The first two stages of overcurrent protection in the P111Enh relay are provided with a timer hold facility, which may either be set to zero or to a definite time value. Setting of the timer to zero means that the overcurrent timer for that stage will reset instantaneously once the current falls below 95% of the current setting. Setting of the hold timer to a value other than zero, delays the resetting of the protection element timers for this period. When the reset time of the overcurrent relay is instantaneous, the relay will be repeatedly reset and not be able to trip until the fault becomes permanent. By using the Timer Hold facility the relay will integrate the fault current pulses, thereby reducing fault clearance time.
The timer hold facility can be found for the first and second overcurrent stages as settings Ι> DMT tRESET» and «Ι>> DMT tRESET», respectively. Note that this cell is not visible for the IEC/IEEE/US curves if an inverse time reset characteristic has been selected (SETTING GROUP x/PROTECTION Gx/ PHASE O/C G1(G2)/ I> (I>>) Reset Delay Type 1:IDMT setting), as the reset time is then determined by the programmed time dial setting.
Reset IDMT Characteristic IEEE/US/IEC
The IEEE/US/IEC curves may have an inverse time reset characteristic (I> (I>>) Reset Delay Type 1: IDMT setting) or instantaneous reset (I> (I>>) Reset Delay Type 0:DMT setting). If IDMT reset is selected (I> (I>>) Reset Delay Type 1: IDMT setting) then the following menu will be available: Ι> (I>>) RTD/RTMS RESET. The following equation can be used to calculate the inverse reset time for IEEE/US/IEC curves:

Note: To be in line with IEEE/US/IEC the RTMS (RTD) value should be equal to the TMS (TD) value. The setting for RTMS or RTD is given to adjust the reset characteristic to specific applications. Typically RTMS = TMS and RTD = TD.

1.2 SOTF: Switch On To Fault (Model A, B, E)
1.2.1 General
In some feeder applications, fast tripping may be required if a fault is still present on the feeder after the reclosure of the circuit breaker (Close on to fault).
In the case of a CB being manually closed, a switch on to an existing fault may occur. This situation is particularly critical because the overcurrent protection element would not clear the fault until the set time-delay has elapsed. It is then desirable to clear the fault as fast as possible.
Enabling and setting the SOTF (Switch On To Fault) function can be done under the SETTING GROUP x/PROTECTION Gx/SOTF? submenu.
Crossing the SOTF Threshold will initiate the SOTF function. The tSOTF time-delay will then be started.
If the SOTF element is set to Trip, Trip-Inrush Bl (AE) or Trip-Latch (AE), it means that it is linked to the Protect.Trip and Prot.Trip pulse functions (see LED and Output configu-ration).
If the SOTF element is set to Alarm, it means that it is linked to the Alarm function (see LED and Output configuration).
If Trip-Inrush Bl (AE) is selected, the SOTF element is blocked via the Inrush Blocking function (refer to Inrush Blocking section).
If Trip-Latch (AE) is selected, the SOTF element will remain high after a trip, until it is reset via a binary input, the HMI or a remote RESET command.
1.2.2 SOTF Description
The following signals can activate the SOTF function:
— manual closing ordered using the HMI (menu or function Close key)
— command generated by a digital input labelled Manual Close,
— front communication Closing command,
— rear communication Closing command,
The diagram below illustrates this functionality.
P111Enh_EN_OP v1.3
Operation (OP) 5-12 MiCOM P111Enh
OP
Figure 2: Switch on to fault logic diagram
When at least one of the signals listed above has been detected, a timer starts and lasts until 52 Unblock.SOTF Time (GLOBAL SETTINGS/CIRCUIT BREAKER submenu) elapses.
Once the above timer has elapsed and the SOTF thresholds have been crossed, the tSOTF settable time-delay starts. This settable time-delay is particularly useful in applications where fault selectivity is required.
This time-delay is also useful in cases where serious transients may be present, where the three poles of the CB do not all close at the same time and in cases where the CB may not close instantaneously.
“tSOTF” can also be considered as a trip time-delay that substitutes itself to the trip time-delay associated with the crossed threshold so that the tripping time is accelerated.
If the SOTF stage is reset before the settable time-delay tSOTF elapses, the SOTF function is reset.

1.3 Earth Fault Protection
The Earth fault element operates from a measured earth fault current quantity.
The first earth fault stage has time-delayed characteristics which are selectable between inverse definite minimum time (IDMT) and definite time (DMT). The second stage has a definite time characteristic only.
If an earth fault stage (IN_1 stage?, IN_2 stage? or IN_3 stage? (E) menu) is set to Trip, Trip-Inrush Bl (AE) or Trip-Latch it means that that stage is linked to the Protect.Trip and Prot.Trip pulse functions (see LED and Output configuration).
If an earth fault stage (IN_1 stage?, IN_2 stage? or IN_3 stage? (E) menu) is set to Alarm, it means that that stage is linked to the Alarm function (see LED and Output configuration).
If Trip-Inrush Bl (AE) is selected, the earth fault stage is blocked via the Inrush Blocking function (refer to Inrush Blocking chapter).
If Trip-Latch (AE) is selected, the earth fault stage will remain after a trip, until it is reset via a binary input, the HMI or a remote RESET command.

1.4 Negative Sequence Overcurrent Protection (Model E)
In traditional phase overcurrent protection schemes, overcurrent thresholds must be set above the maximum load current levels. This limits the sensitivity of the relay. Most protection schemes also use an earth fault element based on residual current, which improves sensitivity for earth faults. However, it can happen that some faults occur and stay undetected by such schemes.
Any unbalanced fault condition will produce negative sequence current. Thus, a negative phase sequence overcurrent element can detect both phase-to-phase and phase-to-earth faults.
The negative phase sequence overcurrent element included in the P111Enh relays provides one stage non-directional overcurrent protection with independent time-delay characteristics. These characteristics are selectable between inverse definite minimum time (IDMT) and definite time (DT). The inverse time-delayed characteristics support both IEC and IEEE curves. Please refer to section 2.1 for a detailed description.
If the I2> protection element is set to Trip, Trip-Inrush Bl or Trip-Latch, it means that that element is linked to the Protect.Trip and Prot.Trip pulse functions (see LED and Output configuration).
If the I2> protection element is set to Alarm, it means that that element is linked to the Alarm function (see LED and Output configuration).
If Trip-Inrush Bl is selected, the negative sequence overcurrent element is blocked via the Inrush Blocking function (refer to Inrush Blocking section).
If Trip-Latch is selected, the negative sequence overcurrent element will remain high after a trip, until it is reset via a binary input, the HMI or a remote RESET command.

1.5 Broken Conductor Detection (Model E)
The relay incorporates an element that measures the ratio of negative to positive phase sequence current (I2/I1). This will be affected to a lesser extent than the measurement of negative sequence current alone, since the ratio is approximately constant with variations in load current. Hence, a more sensitive setting may be achieved. The logic diagram is as shown below. The ratio of I2/I1 is calculated and compared with the Ratio I2/I1 threshold. If it exceeds the threshold then the time-delay tBCond is initiated. The Brkn Cond I< block signal is used to disable Broken Conductor function if the max current value from three phases is too low. The Brkn Cond I< block undercurrent threshold is settable (GLOBAL SETTINGS/O/C ADVANCED/[46BC] Brkn.Cond I< Block.). Factory setting value is 0.1 In.
Figure 5: Broken conductor protection logic
The Broken Conductor function can be set to: Trip, Trip-Inrush Bl, Trip-Latch or Alarm.
If the Broken Conductor element is set to Trip, Trip-Inrush Bl or Trip-Latch, it means that it is linked to the Protect.Trip and Prot.Trip pulse functions (see LED and Output configuration).
If the Broken Conductor element is set to Alarm, it means that it is linked to the Alarm function (see LED and Output configuration).
If Trip-Inrush Bl is selected, the I2/I1 threshold is blocked via the Inrush Blocking function (refer to Inrush Blocking section).
If Trip-Latch is selected, the Broken Conductor element will remain high after a trip, until it is reset via a binary input, the HMI or a remote RESET command.

1.6 Thermal Overload Protection (Model N, A, B, E)
The relay incorporates a current-based thermal replica, using r.m.s. load current to model heating and cooling of the protected plant. The element can be set with both alarm and trip stages.
The heat generated within an item of plant, such as a cable or a transformer, is the resistive loss (I2R x t). Thus, heating is directly proportional to current squared. The thermal time characteristic used in the relay is therefore based on current squared, integrated over time. The relay automatically uses the largest phase current for input to the thermal model.
The equipment is designed to operate continuously at a temperature corresponding to its full load rating, where the generated heat is balanced by heat dissipated through radiation, etc.
Over-temperature conditions therefore occur when currents in excess of the rating are allowed to flow for a period of time. It can be shown that temperatures during heating follow exponential time constants and a similar exponential decrease of temperature occurs during cooling.
This characteristic is used to protect cables, dry type transformers (e.g. type AN), and capacitor banks.
The thermal time characteristic is given by:
−=

Where:
t Trip = Tripping time (in seconds)
Te = Thermal time constant of the equipment to be protected (in seconds)
K = Thermal overload equal to therm

Ieq = Equivalent current corresponding to the R.M.S. value of the largest phase current
IP = Steady state pre-loading current before application of the overload
Itherm = Setting value. It is full load current rating
θP = Steady state pre-loading thermal state before application of the overload
θalarm = Initial thermal state. If the initial thermal state = 30% then θ =0.3
θtrip = Trip thermal state. If the trip thermal state is set at 100%, then θ trip = 1
The tripping time varies according to the load current carried before application of the overload, i.e. whether the overload was applied from ‘hot” or “cold”.
The parameter settings are available in the various menus. The calculation of the thermal state is given by the following formula:

Where θ is the thermal state and is θp the pre-fault thermal state.
Note: A current of 105% Ιs (kΙFLC) has to be applied for several time constants to cause a thermal state measurement of 100%.
Figure 6: Thermal overload protection logic
The functional block diagram for the thermal overload protection is shown in Figure 7
The magnitudes of the three phase currents are compared and the largest magnitude selected as the input to the thermal overload function. If this current exceeds the thermal trip threshold setting a start condition is asserted.
The Thermal Trip signal remains high until the thermal state drops below the thermal reset threshold.
The thermal reset threshold is settable using the Theta Trip/Reset Ratio value.
The Thermal Reset Ratio is calculated:
Thermal Reset Threshold = Theta Trip/Reset Ratio x Theta Trip
For Theta Trip/Reset Ratio = 90% (0.9) and Theta Trip=120%:
Thermal Reset Threshold = 0.9 x 120%=108%
If the Thermal State is above the Theta Trip threshold and then drops, the Thermal Trip signal will reset when the Thermal State drops below the Thermal Reset Threshold (see above).
If Blocking Ithermal Input (ABE) is in high state, for calculation Thermal Characteristic uses current value 0xIn instead of measured value.
Thermal protection also provides an indication of the thermal state in the MEASUREMENTS column of the relay. The thermal state can be reset by either an opto-input (if assigned to this function using the programmable scheme logic) or the relay menu.
The reset function in the menu is also found in the MEASUREMENTS column with the thermal state menu.

1.7 Circuit Breaker Failure Function: CB Fail
The circuit breaker failure protection function incorporates one timer allowing configuration for the following scenario: upon any protection trip, CB Fail Timer tBF is started, and normally reset when the circuit breaker opens to isolate the fault. If breaker opening is not detected, CB Fail Timer tBF times out and closes an output contact assigned to tCBF. This contact is used to backtrip upstream switchgear, generally tripping all infeeds connected to the same busbar section.
The complete breaker fail logic is illustrated in Figure 8.
Figure 7: Circuit Breaker Failure protection logic
The CBF element CB Fail Timer tBF operates for trips triggered by protection elements within the relay or via an external protection device (binary input). The latter is achieved by assigning one of the relay opto-isolated inputs to AUX n (ABE) set for tripping or Strt tBF (ABE) (depends on the application).
When CBF is triggered by a current-based protection element included in the P111Enh, it is reset by an undercurrent element (I<Threshold CBF or IN< Threshold CBF) only.
When it is triggered via the AUX n (ABE) input, CBF is reset by an undercurrent element.
When it is triggered via the Strt tBF input (ABE), CBF is reset by the low state of this input only.
The Block I>? (E) and Block IN>? (E) settings are used to cancel starts issued by the overcurrent and earth fault elements, respectively, following a breaker fail time out. The start is cancelled when the cell is set to Yes.
If the Retrip option is selected for the CB Fail function, it means that it is linked to the Protect.Trip and Prot.Trip pulse functions (see LED and Output configuration).
If CB Fail is set to Alarm, any outputs and LEDs assigned to the Alarm or tCBF function are energized.
If CB Fail is not set to Disabled, any outputs and LEDs assigned to the tCBF function are energized.

1.8 Auxiliary Timers (available in B, A and E)
Four auxiliary timers, tAux1, tAux2, tAux3 and tAux4, are available and associated with logic inputs Aux1, Aux2, Aux3 and Aux4 (refer to the SETTING GROUP x/INPUTS CONFIGURATION menu). When these inputs are energized, the associated timers start and, when the set time has elapsed, the associated LEDs (SETTING GROUP 1(2)/LEDs CONFIGURATION menu) are lit or/and the associated output relays close (refer to the SETTING GROUP 1(2)/OUTPUT RELAYS CONFIGURATION menu). Time-delays can be independently set from 0 ms to 600 s.
Each auxiliary timer can be set independently to:
— Alarm: Alarm signal
— Trip: Protection Trip signal
— Trip-Inrush Bl (AE): Protection Trip signal with inrush blocking
— Trip-Latch(AE): Protection Trip signal latched until it is reset via a binary input (Reset Ltch Sign), the HMI or a remote reset command
— Load Shedding (E): The high state of an AUX logic input starts the corresponding tAUX timer at the expiry of which it is associated with the Trip CB Order and tAUX outputs (refer to the SETTING GROUP 1(2)/OUTPUT RELAYS CONFIGURATION menu). Additionally this state (Load Shedding state) is stored in memory. The stored value is reset by any protection trip, a close signal or the CB closed status (CB status 52A logic input) (refer to chapter P111Enh/EN AP – Application).
— AR after LS Hi (E): If the Load Shedding state is stored, the high state of the logic input triggers the tAUX timer. When the set value has elapsed the close command is executed (Close CB order output) (refer to chapter P111Enh/EN AP – Application).
— AR after LS Lo (E): If the Load Shedding state is stored, the low state of the logic input triggers the tAUX timer. When the set value has elapsed the close command is executed (Close CB order output) (refer to chapter P111Enh/EN AP – Application).
In the SETTING GROUP x/INPUTS CONFIGURATION (ABE) menu AUX5 (ABE) and/or AUX6 (ABE) can be mapped to inputs. These input functions have no timers (instantaneous action). They can be used as bridges between inputs and LEDs or inputs and outputs. It is not possible to link this input function to a Trip or Alarm signal.

1.9 Logic Selectivity (Model E)
Section 1.9 describes the use of non-cascade protection schemes that make use of start contacts from downstream relays connected to block operation of upstream relays. In the case of Logic Selectivity (Sel), the start contacts are used to raise the time-delays of upstream relays, instead of blocking them. This provides an alternative approach to achieving non-cascade types of overcurrent scheme. This may be more familiar to some utilities than the blocked overcurrent arrangement. The Logic Selectivity function provides the ability to temporarily increase the time-delay settings of the second and third stages of phase overcurrent and measured earth fault protection elements.
Two independent Logic Selectivity functions are available: Sel1 and/or Sel2.
This logic is initiated by energization of the appropriate binary input assigned to Sel1 (Sel2)
To allow time for a start contact to initiate a change of setting, the time settings of the second and third stages should include a nominal delay.
This function acts upon the following protection functions:
— Phase overcurrent (2nd and/or 3rd stages)
— Earth fault (2nd and/or 3rd stages)
The logic diagram for the selective overcurrent function is shown for phase A of the third overcurrent stage. The principle of operation is identical for the 3-phase phase overcurrent element, stages 2 and 3, and the earth fault element, stages 2 and 3. When the selective logic function is enabled, the action of the blocking input is as follows:
1. No block applied In the event of a fault condition that continuously asserts the start output, the function will assert a trip signal after the normal time-delay tI>>> has elapsed.
2. Logic input block applied In the event of a fault condition that continuously asserts the start output, the function will assert a trip signal after the selective logic time-delay tSelx has elapsed.

1.10 Cold Load Pick Up
The Cold Load Pick-up feature allows selected settings of MiCOM P111Enh relays to be changed to react to temporary overload conditions that may occur during cold starts. This condition may happen by switching on large heating loads after a sufficient cooling period, or loads that draw high initial starting currents.
When a feeder is energized, the current levels that flow for a period of time following energizing may differ greatly from the normal load levels. Consequently, overcurrent settings that have been applied to give short circuit protection may not be suitable during this period.
This function acts upon the following protection functions:
— Phase overcurrent (1st, 2nd and 3rd stages)
— Earth fault (1st, 2nd and 3rd stages (E))
— Broken Conductor I2/I1 element (E)
— Thermal Overload Itherm setting (NABE)
— Negative sequence overcurrent (E)
The Cold Load Pick-up (CLP) logic raises (x Level%) the settings of selected stages for a set duration (tCL). This allows the protection settings to be set closer to the load profile. Cold load pick-up cannot restart until the end of tCL duration. The CLP logic provides stability, without compromising protection performance during starting.
CLP is started by a digital logic Cold Load PU binary input or/and by current stage. It depends on the configuration (see Fig.11):
— Cold Load PU?: 1: Cur.+Input — CLP is started from both: current criteria (stages I<5%In and I>10%In) and binary input criteria (Cold Load PU Binary Input). If Cold Load PU function is not assigned to any inputs, CLP is started from current criteria only,
— Cold Load PU?: 1: Input — CLP is started from binary input criteria (Cold Load PU Binary Input). If Cold Load PU function is not assigned to any inputs, CLP is disabled.
Typically Cold Load PU Binary Input is wired to 52A CB status.

1.11.2 Logic Inputs
The auto-reclose function has four inputs that can be assigned to the auto-reclose logic. These inputs can be mapped to opto-isolated inputs in the SETTING GROUP x/PROTECTION Gx/INPUT CONFIGURATION menu. External contacts can then be wired to these inputs and influence the auto-recloser scheme. These four logic inputs are:
— one external CB FLT Ext Sign. – external information that CB is not ready to close (a spring not charged, too low level of CB gas, etc),
— AUX 1 or AUX 2 assigned to trip and [79] shots — the external starting commands,
— Block [79] – the external blocking command (for example: an external switch).
The following table gives the “SETTING GROUP 1(2)/INPUT CONFIGURATION 1(2)” menu assigned to the auto-reclose logic input.

1.11.2.1 External CB faulty signal
Most circuit breakers provide one trip-close-trip cycle. A time-delay is necessary for the CB to return to its nominal state (for example, the spring that allows the circuit breaker to close should be fully charged). The state of the CB can be checked using an input assigned to the CB FLT Ext.Sign. function. If the CB FLT Ext.Sign. signal is detected during Closing time, the Auto-reclose Close Command is interrupted and blocked and the CB remains open. In this case the Autorecloser will be Lockout by not successful close command monitored by Auto-reclose CB Supervision logic (it’s separate function to CB Supervision in GLOBAL SETTINGS/CIRCUIT BREAKER column). If, on completion of the tCB FLT ext time (GLOBAL SETTINGS/CIRCUIT BREAKER submenu), the CB FLT ext (Alarm) indicates a failed state of the CB, a lockout occurs and the CB remains open.

1.11.2.2 External Starting Commands
Two independent and programmable inputs (AUX1 and AUX2) can be used to initiate the auto-reclose function from an external device (such as an existing overcurrent relay). These logic inputs may be used both independently and in parallel with the overcurrent elements.
Note:
1. The input must be assigned to an AUXx function (SETTING GROUPx/INPUT CONFIGURATION Gx),
2. AUXx must be set to Trip (SETTING GROUP x/PROTECTION Gx/AUX TIMERS Gx/AUXx?) and time-delay tAUXx must be configured (instantaneous: tAUXx set to 0 s),
3. The tAUXx Close Shot cell must be set for every cycle (Close shot).
1.11.2.3 Internal and External Blocking Commands
The auto-recloser can be blocked by an internal or an external control. It can be used when protection is needed without requiring the use of the auto-reclose function.
The external block is executed by the Block [79] input, Blocking via RS485, [79] default cell in CTRL line, or temporary blocked after a close command made by an operator until Time Inhibit tI on Close set in GLOBAL SETTINGS/ [79] ADVANCED SETTINGS column.
The internal block can be executed by a final trip, a number of valid A/R rolling demands or an A/R conflict.
A typical example is on a transformer feeder, where the auto-recloser may be initiated from the feeder protection device but needs to be blocked on the transformer protection side.
1.11.3 Auto-reclose Output Information
The following output signals can be mapped to an LED (see SETTING GROUP x /LEDS CONFIGURATION Gx menu) or to output relays (see SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx menu) in order to provide information about the status of the auto-reclose cycle:
— Auto-reclose cycle in progress
— Final Trip
— Internal block
— External block
— Auto-reclose successful

1.11.3.2 Final Trip
The «Final trip» signal indicates that a complete auto-reclose cycle has been performed and that the fault has not been cleared.
The «Final trip» signal can be reset after a manual closing of the CB after the settable Inhibit Time tI on Close (GLOBAL SETTINGS/ [79] ADVANCED SETTING) time-delay or reset via a Reset Command (assigned Binary Input, RS485 Reset Latched Signaling command , C clear key).
1.11.4 Auto-reclose Logic Description
The auto-reclose function makes it possible to automatically control the the CB’s reclosing cycles (two, three or four shot cycle, settable using the Close Shot ? parameter – separate for each protection element (SETTING GROUP x/PROTECTION Gx/[79] AUTORECLOSE G1(2) menu).
Dead times for all the shots (reclose attempts) can be independently adjusted.
The number of shots is directly related to the types of fault likely to occur on the system and the voltage level of the system (for instance medium voltage networks).
The Dead Time (tD1, tD2, tD3 and tD4) and the minimum drop-off time start when the CB has tripped (when the 52a input has dropped off – Start Dead t on 1: CB trips or the protection element has reset — Start Dead t on 0: Protect.Reset configuration option). The Dead Time is set to initiate the auto-recloser when the circuit breaker is opened.
At the end of the relevant dead time the close command (Close CB Order) is executed and the CB supervision timer is started. The length of this timer is equal to: tClose Pulse (GLOBAL SETTINGS/CIRCUIT BREAKER) + 150 ms (Auto-reclose CB Supervision logic). If the CB is not closed after this time-delay, the auto-recloser is locked out ([79] Lockout) and the Alarm is issued (Alarm CB Time Monitor).
The reclaim time (Reclaim Time tR) starts when the CB has closed. If the circuit breaker does not trip again, the auto-reclose function resets at the end of the reclaim time.
If a protection element operates during the reclaim time, the relay either advances to the next shot programmed in the auto-reclose cycle, or it locks out (see Inhib.Trip function description).
The total number of reclosures is displayed in the RECORDS /COUNTERS/ AUTORECLOSE COUNTER menu cell.
1.11.5 Auto-reclose Inhibit Trip
Freely settable the inhibit of the trip after closing command issued via the [79], set separately for each protection element:
tI>, tI>>, tI>>>, tIN_1, tIN_2, tIN_3, tAUX1, tAUX2
The trip inhibit is used for following cases:
— e/f protection in neutral-insulated or compensated systems. The [79] can clear a non-permanent fault in the first cycles. If it will be permanent fault, there will be no the final trip up to reset of the protection trip. For 4-cycle [79]: Inhibit Trip 1000 setting. In the first three cycles (000) the trip is executed to allow fault clearance, but the last one (1) is with inhibition, so no trip is executed in case of permanent fault).
— application where for example the setting for the I> stage covers more than the protected zone, so that the [79] can clear faults downstream too, but the final trip will be executed by the downstream relay or a fuse, therefore in the upstream relay, tI> should be inhibited – waiting for tI>> trip of the downstream relay). Note: for this case Fast Trip O/C function can be used too (see below).
Operation
P111Enh_EN_OP v1.3 MiCOM P111Enh (OP) 5-27
OP
Inhibit Trip setting:
— 0: means that after close via the [79], the protection element trip will be not inhibited (function is disabled).
— 1: means that after close via the [79], the protection element trip will be inhibited.
It is recommended to set another protection stage with setting for Alarm only, to inform that this fault was not cleared by autorecloser so it’s still present (tripping from this protection element is inhibited). For above case when the auto-reclose is successful, the reset of inhibition is applied after reset of protection stage (current below the stage value). For another case when during inhibition of protection element, another protection element (set to run [79]) makes a trip after going to the next cycle (the next [79] close command is executed) the inhibition is reset and the further action depends on the configuration:
if in the next cycle this protection element is still set with inhibition, the protection element is still inhibited
if in the next cycle this protection element is not set with inhibition, but the fault is still not cleared, this protection element will trip CB (If another protection element moves auto-reclose to the next cycle, the inhibition is removed automatically and [79] logic checks configuration for the next [79] shot).
1.11.6 Auto-reclose Fast Trip
On circuits using time-graded protection, the auto-recloser allows the use of instantaneous (fast) protection (Fast O/C Trip function in SETTING GROUP x/PROTECTION Gx/[79] AUTORECLOSE Gx menu) to issue a high speed first trip. With fast tripping, the duration of the power arc resulting from an overhead line fault is reduced to a minimum, thus lessening the chance of damage and of the transient fault developing into a permanent fault. To avoid maloperation because of transients, it is possible to assign a short time-delay to the fast trip: Fast O/C Trip Delay setting (SETTING GROUP x/PROTECTION Gx/[79] AUTORECLOSE Gx menu column) above the typical transient time value. The fast trip can be associated with phase-to-phase faults (Fast O/C Trip) and/or earth faults (Fast E/Gnd Trip), separately for every shot in the auto-reclose sequence. If in Fast O/C Trip configuration the setting for chosen trip shot is ‘ 0 ‘, the trip is executed after the time-delay of the protection element. If it is set to ‘ 1 ‘, the time-delay set in the Fast O/C Trip Delay menu cell is applied. In some regions the typical setting of the fast trip for a 2-shot AR is set:
— Fast O/C Trip (trip shots): 00011 (The first and second trips with Fast O/C Trip Delay to reduce to minimum the resulting power arc; The third – final – trip after the time-delay of the protection element to ensure the grading in the power system – trip selectivity)
— Fast E/GND Trip (trip shots): 00000 (alls trips re executed after the time-delays of the protection elements).
Fast O/C Trip – refers to all O/C stages in the PHASE O/C menu column: I>, I>>, I>>>.
Fast E/GND Trip – refers to all E/GND stages in the PHASE E/GND menu column: IN_1, IN_2, IN_3.
Fast O/C (E/GND) Trip Delay is associated with a DMT characteristic even if the protection element is set to an IDMT characteristic. For the fast trip the reset time-delay of the protection element is not applied.
1.11.7 Auto-reclose Inhibit after Manual Closing
The Inhibit Time tI on Close timer (GLOBAL SETTINGS/ [79] ADVANCED SETTING) can be used to block the auto-reclose cycle being initiated after the CB has been manually closed onto a fault. The auto-recloser is blocked for the duration of Inhibit Time tI on Close after a manual CB Closure.
1.11.8 Recloser Lockout
If a protection element operates during the reclaim time, following the final reclose attempt, the relay will lockout and the auto-reclose function will be disabled until the lockout condition is reset.
P111Enh_EN_OP v1.3
Operation (OP) 5-28 MiCOM P111Enh
OP
The lockout condition is reset by a manual closing after the Inhibit Time tI on Close timer elapses.
Additionally the lockout condition is reset by a reset signalling command (via Inputs, HMI key, Remote Reset command),
The auto-recloser can also be locked out using a CB FLT Ext.Sign. input. This information can be issued from the «not charged» or «Low gas pressure» indications of CB springs.
Note that the auto-recloser can also be locked out by:
• The fact that the CB does not open after the tBF delay (CB Fail) elapses,
• An operating time longer than the set thresholds,
• Local or remote manual Close or Open command when the auto-reclose is in progress,
• The Rolling Demand function detects too many auto-reclose shots.
• CB monitoring logic detects abnormal CB position (opened and closed, or not opened and not closed) for longer than set: Max CB Close or Max CB Open time.
In the lockout condition the ALARM with the cause: ALARM [79] Lockout is displayed up to reset of the lockout condition.
1.11.9 Setting Group Change when the auto-reclose is in progress
During the auto-reclose cycle, if the relay receives a command to switch setting groups, it is executed after the end of auto-reclose action (if auto-reclose is not in progress).
1.11.10 Rolling Demand
This specific counter avoids frequent operations of a CB in case of intermittent faults. The numbers of shots can be set from 2 to 100 in the cell Max cycles No. Rol.Demand, settable over a time period (GLOBAL SETTINGS/ [79] ADVANCED SETTING /Time period Rol.Demand) from 1 min to 24 hours.
The rolling demand is used when a defined number of successful recloses are performed over a defined time. If it is happened auto-reclose function is Lockout and he ALARM with the cause: ALARM [79] Roll.Demand is displayed up to reset the lockout condition.
If after Alarm [79] Rolling Demand signaling, the lockout condition reset is applied, the recorded number of rolling demand shots are cleared.
1.11.11 Signalling Reset after Close via 79
In the GLOBAL SETTINGS/ [79] ADVANCED SETTING menu it is possible to set the signalling reset after a close command executed by the auto-recloser. If Signalling Reset is set to 1: Close via 79, after the auto-recloser’s close shot (confirmed by the 52a CB status), signalling (LEDs, display) of the last trip before the close shot is reset:
— Latched LEDs
— Trip information on the P111Enh’s front panel
— Electromagnetic Flag Indicators on the Front Panel
— Latched outputs
This function signals the final trip only and clears signalling if the CB remains closed (Auto-reclose is successful). This function is recommended if the P111Enh is integrated into a SCADA system or if the substation is rarely supervised by maintenance personnel. In this case it is not necessary to clear signalling if the fault has disappeared and the line is healthy.
Note: Reset of signalling and of latched outputs can be done using the General resetting function.
Operation
P111Enh_EN_OP v1.3 MiCOM P111Enh (OP) 5-29
OP
This configuration can be set in the GLOBAL SETTINGS/LOC submenu:
— LEDs Reset:
— 0: Manual only (via Inputs, HMI key, Remote Reset command)
— 1: Start protect. (Start of the protection element set to Trip)
— Ltchd Outp. Reset:
— 0: Manual only (via Inputs, HMI key, Remote Reset command)
— 1: Start protect. (Start of the protection element set to Trip)
The Manual only option prevents a close command from being issued without readout of the cause of trip by maintenance personnel. It reduces the risk to switch on to fault.
The Start protect option allows signalling of the latest trip only.
1.12 External Trip via a Binary Input (Model A, B and E)
For some applications it is necessary to issue a CB trip via a binary input. Any input assigned to AUXn (n = 1-4) can be used to that effect. The AUX function must be set to Trip.
Tripping is executed after a set time-delay: tAUXn (n = 1-4).
Auxiliary voltage connected to such a configured Input energizes output relays assigned to Protect.Trip, Prot.Trip pulse or tAUX AUXn (n = 1-4).
The Low Energy Trip Coil output and/or Flag Indicator output are activated if they are assigned to Protect.Trip or tAUX AUXn (n = 1-4) (refer to Figure 9 — AUX timers logic)

1.13 Blocking Logic Function and Blocked Overcurrent Scheme Logic (Model ABE)
Each stage of the phase protection element can be blocked via an appropriately configured binary input. Binary inputs can be assigned to the following functions (SETTING GROUPx/INPUT CONFIGURATION Gx ):
— Block.tI> (ABE)
— Block.tI>> (ABE)
— Block.tI>>> (ABE)
— Block.tSOTF (ABE)
— Block.tIN_1 (ABE)
— Block.tIN_2 (ABE)
— Block.tIN_3 (E)

— Block.tBrkn Cond (E)
— Block.Itherm (ABE)
— Block.AUX1 (ABE)
— Block.AUX2 (ABE)
— Block.AUX3 (ABE)
— Block.tCB Fail (ABE)
— Block. [79] (E)
Such a configured input can be used by the blocking logic function or by a protection element disabling function (Auto-reclose (E), CB Fail or AUX (ABE)).
The blocking logic function can be applied to radial feeder circuits where there is little or no back feed. For parallel feeders, ring circuits or where there can be a back feed from generators, directional relays should be considered.
The blocking logic function allows the upstream IDMT relay to be blocked by the start output of a downstream relay that has detected the presence of a fault current above its threshold. Thus both upstream and downstream relays can have the same current and time settings, and the blocking feature will automatically provide grading.
If in SETTING GROUPS x/PROTECTION Gx/[[50BF] CB Fail the function: Block I> (IN>)? (E) is set to 0: Yes and the Circuit Breaker Fail protection is enabled, the blocking command on the upstream relay will be removed if the downstream circuit breaker fails to trip.

1.14 Inrush Blocking (Model A and E)
The Inrush Blocking function measures the ratio of second to fundamental harmonic currents. It can be used as a “blocking logic” of I>, I>>, I>>>, IN_1, IN_2, IN_3 (E), I2 > (E), SOTF, Broken Cond (E), CB Fail, and AUXn in cases where the 2nd harmonic ratio is higher than the settable threshold. Indeed, inrush blocking functions will reset the selected protection function starts.
Blocked by the second harmonic ratio of a protection element is set in the main setting cell for that element (for example: I>? 3: Trip-Inrush Bl). Each protection element set to 3: Trip-Inrush Bl will be blocked by the Inrush current function.
The minimum duration of an overcurrent threshold inhibition (tReset) can be also set. This value depends on the transformer power transient inrush duration: between 0.1 second (for a 100 kVA transformer) to 1.0 second (for a large unit). It is used to avoid any maloperation during a fixed time period in case of too sensitive a setting.
1.14.1 Operation
For each of the three phases currents (IA, IB, IC), the harmonic restraint function compares the ratio of 2nd harmonic to the fundamental with the set ratio (Harmonic 2 / Fundamental settable from 10 % up to 50 % in steps of 1%).
The minimum fundamental current value required for operation of the Inrush Blocking function is 0.2 In, and there is no upper limit to disable this feature. However, in transformer protection, the high set overcurrent stage shall not be controlled by this Inrush Blocking feature; this enables detection of all high current faults without inrush blocking.
It is possible to set two options for Inrush Current logic in the GLOBAL SETTINGS/INRUSH BLOCKING/Inrush Blocking? menu:
— 1: Yes – monitoring is permanent. The Inrush Blocking function will block the selected protection stages every time inrush conditions are present on the line (Ratio of 2nd Harmonics measured greater than Inrush H2 set ratio), and will be active at least for the duration of Inrush Reset Time. This timer defines the minimum duration of overcurrent threshold inhibition (0-200 s, settable). This timer starts as soon as operating inrush current threshold picks up:
• If the inrush condition lasts less than the set value for Inrush Reset Time, the selected overcurrent function will be inhibited for the duration of Inrush Reset Time.
• If the inrush condition lasts longer than the set value for Inrush Reset Time, the selected overcurrent function will remain inhibited as long as the inrush condition is present.
— 2: Closing – monitoring is based on the Close CB order output. The Inrush Blocking function will block the selected protection stages every time a close command is executed and the Ratio of measured 2nd Harmonics is greater than the set Inrush h2 ratio, and will be active at least for the duration of Unblock Inrush Time.
Note: Inrush Blocking in P111Enh relays is not phase-selective. If an inrush condition occurs on any phase, the selected protection stages will be blocked in all 3 phases.

2. OPERATION OF NON PROTECTION FUNCTIONS 2.1 Circuit Breaker State Monitoring (Model A and E)
An operator at a remote location requires a reliable indication of the state of the switchgear. Without an indication that each circuit breaker is either open or closed, the operator has insufficient information to decide on switching operations. The MiCOM P111Enh relays incorporate circuit breaker state monitoring, giving an indication of the position of the circuit breaker.
This indication is available either on the relay front panel or via the communication network.
The CB positions can be selected at SETTING GROUPx/INPUT CONFIGURATION Gx):
— CB status 52A
— CB status 52B
If two inputs are assigned to both the above inputs, CB status is based on both indications.
If only one function is used, CB status is based on a single-bit information only (the second is derived from the first one).
If CB Supervision function is activated (GLOBAL SETTINGS/CIRCUIT BREAKER/CB Supervision?: 1:Yes), CB monitoring logic detects abnormal CB’s position (opened and closed, or not opened and not closed) in the monitoring window: the max value from settings: Max CB Close Time or Max CB Open Time (GLOBAL SETTINGS/CIRCUIT BREAKER column). CB monitoring logic checks CB position permanently, if an abnormal CB status is detected by the time longer than the monitoring window, the Alarm is issued (Alarm State of CB).
The CB’s status can be displayed on the P111Enh front panel using programmable LEDs. To assign an input to the CB status, an AUX function must be used.
For example:
L1 is assigned to CB status 52a and AUX5
L2 is assigned to CB status 52a and AUX6
LED 7 is assigned to AUX5
LED 8 is assigned to AUX6
In the above configuration LED7 indicates the CB closed position and LED8 indicates the CB open position.
If the Control menu cell is selected as the default display, the CB status is indicated on the LCD display:
CB status: Opened CTRL: no operat.

For the proper collaboration with CB coils, in menu it is possible to set:
— trip pulse time (GLOBAL SETTINGS/CIRCUIT BREAKER/tOpen pulse)
— close pulse time (GLOBAL SETTINGS/CIRCUIT BREAKER/tClose pulse)
The trip pulse time is used by: Protect.Trip pulse and Trip CB Order output functions.
The close pulse time is used by: Close CB Order output functions.
In cases where the breaker is tripped by an external protection device it is also possible to update the CB condition monitoring. This is achieved by setting one of the AUX protection element (Protect.Trip) or Manual Trip logic inputs or via the communications to accept a trigger from an external device.

2.3 Local / Remote Mode (Model A and E)
The goal of this feature is to make it possible to block commands sent remotely through communication networks (such as setting parameters, control commands, etc.), so as to prevent any accidents or maloperations during maintenance work performed on site.
Local Mode can be achieved by:
— Control Mode default cell in the menu (E):
LR Status:L+R CRL: no operat.
— A digital input labelled: Local CTRL Mode
When the Local CTRL Mode input is energized, all remote commands are blocked. When the Local CTRL Mode input is de-energized, remote control commands can be issued. In Local mode, only the synchronizing time signal is allowed.
The Remote mode is set at GLOBAL SETTINGS/CIRCUIT BREAKER/Remote CTRL Mode:
— 0: Remote only – Only Remote control is permitted. All manual controls (HMI, Close/Trip function keys, Binary Inputs assigned to Manual Close or Trip) are blocked.
— 1: Remote + LOC — Remote and Local controls are permitted.
Control Mode default cell (E):
The first line of CTRL Mode cell allows monitoring of the Local/Remote Mode status:
— Status: Local — Local mode
— Stat:Remote – Remote Mode. GLOBAL SETTINGS/CIRCUIT BREAKER/Remote CTRL Mode is set to 0: Remote only.
— Status: L+R – Remote Mode. GLOBAL SETTINGS/CIRCUIT BREAKER/Remote CTRL Mode is set to 1: Remote + Loc.
The second line is used to change Local/Remote Mode in the menu:
— CTRL: no operat. – No operation
— CTRL: Local – Local Mode command
— CTRL: Remote – Remote Mode command
To change from Remote to Local mode it is necessary to press the OK key, enter Control Password (if it is set), press the OK key twice (confirm password and select changing). Press down or up key to choose Local confirm by Enter. LR Status indicates: LR Status: Local.
To change from Local to Remote mode it is necessary to press the OK key, enter Control Password (if it is set), press the OK key twice (confirm the password and select the change). Press the or key to select Remote then confirm by pressing the OK key. LR Status indicates: LR Status L+R (option Remote CTRL Mode 1: Remote + Local) or LR Status Remote (option Remote CTRL Mode 0: Remote) .
Note: if the Control Password is set to zero: no asking about password will appear – the Control Password is disabled.
It is possible to map the Local Mode state to a LED by assigning the LED to the Local CTRL Mode function (SETTING GROUP x/LEDs CONFIGURATION Gx).

2.4 Setting Group Selection
MiCOM P111Enh relays have two protection setting groups called PROTECTION G1 and PROTECTION G2. Only one group is active at any time.
If a group is used in an application it is possible to remove the other group from the menu in order to simplify the setting procedure. If one group only is chosen the relay uses Group 1 even if the other parameters are set to Group 2 (Inputs(ABE), Menu, Remote Group Setting).
The selection of the number of groups is done at GLOBAL SETTINGS/SETTING GROUP SELECT/ Number of Groups: 1: One Group or 2: Two Groups.
If 1: One Group is selected, the SETTING GROUP 2 column and the setting group cell are hidden in the menu.
Switching between groups can be done via:
— a selected binary input (ABE) assigned to the Setting Group 2 logic input (SETTING GROUP x/INPUTS CONFIGURATION Gx submenu),
— the relay front panel interface (GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group: 1: Group1 or 2: Group2),
— through the communications port (refer to the Mapping Database for detailed information).
Switching between setting groups can be done even while a protection function is active, but it resets all timers, LEDs or flag’s on P111Enh front panel).
The user can check which one of the setting groups is active in the OP PARAMETERS menu: Active Set Group cell.
The user can also assign the active group (Setting Group x function) to an output relay (SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx) or to an LED (SETTING GROUP x/LEDs CONFIGURATION G1).
Setting group change via a digital input
It is possible to change the setting group by energizing a digital input (ABE) (operates on level: logic input is low – setting group 1, logic input is high – setting group 2 ).
If the setting group switchover is done via a binary input (ABE), the change from Group 1 to Group 2 is executed after the set time-delay: t Change Setting G1->G2 (GLOBAL SETTINGS/SETTING GROUP SELECT) (ABE). The switch from Group 2 back to Group 1 is instantaneous.
Warning: If the digital input that has been assigned to the setting group change operates on level (low or high), it is not possible to change the setting group via remote communications.
Switch between Active Groups via a Binary Input (ABE)
When powering up the relay, the selected group (Group 1 or Group 2) corresponds to the state of the logic input assigned to Setting Group 2. This means:
A – Reverse Inp.Logic = 0 and Setting Group 2 = 1 (SETTING GROUP x/INPUTS CONFIGURATION Gx submenu),
If the programmed logic input starts being supplied with +V, then after the t Change Setting G1->G2 time-delay the active group will be G2. If the programmed logic input is not supplied with +V , then the active group will be G1.
B – Reverse Inp.Logic = 1 and Setting Group 2 = 1 (SETTING GROUP x/INPUTS CONFIGURATION Gx submenu),
If the programmed logic input is supplied with +V, then the active group will be G1. If the programmed logic input stops being supplied with +V , then after the t Change Setting G1->G2 time-delay the active group will be G2.
P111Enh_EN_OP v1.3
Operation (OP) 5-38 MiCOM P111Enh
OP
Notes:
1. Binary Input configuration is associated with both Setting Groups, so that if in a Setting Group the selected binary input is assigned to Setting Group 2, in the other group it must be set to Setting Group 2 as well, otherwise no switch will occur.
2. If the P111Enh is powering up (from the currents or the auxiliary voltage) and Group 2 is selected via a binary input, the t Change Setting G1->G2 time-delay is ignored (changing to setting group 2 is instantaneous – without time-delay).
3. The setting group switch is based on the level of the binary input. So as long as Setting Group 2’s logic signal is high, the P111Enh uses Setting Group 2.
Switch between Active Groups via the Menu or a Remote Command (RS485, USB)
By using the relay front panel interface it is possible to change the active setting group: 1: Group1 or 2: Group2 (menu cell: GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group).
This menu cell is commonly used for switching groups from the front panel interface and via a remote command (RS485 or USB).
It means that if the GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group menu cell is set to 1: Group1 and the remote setting group 2 command is executed, the value of menu cell: GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group will be changed to 2: Group2 (Active group: 2).
Setting group 1 will be applied if:
— 1: Group1 is set in the GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group menu cell from the relay’s front panel interface,
— the remote setting group 1 command is executed. The value of the GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group menu cell will then be changed to 1: Group1.
Priority
Warning: If the digital input that has been assigned to the setting group change operates on level (low or high), it is not possible to change the setting group via neither remote communications nor the front panel.
The detailed logic table for setting group selection is shown below:
Binary Input Setting Group 2 (ABE)
Front Panel and Remote Setting

Note: If a setting group change initiated by a remote command has not been effected due of priority settings, that command is ignored (not recorded in the P111Enh’s logic for the future, when priority settings allow changing).
It is possible to assign an Active Group state to an output contact by setting the output contact to the Setting Group x output (SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx.

2.5 Trip Circuit Supervision (Model A and E)
The trip circuit extends beyond the relay’s enclosure and passes through more components, such as fuses, wires, relay contacts, auxiliary switch contacts and so on.
These complications, coupled with the importance of the circuit, have directed attention to its supervision.
The simplest arrangement for trip circuit supervision contains a healthy trip lamp in series with a resistance placed in parallel with the trip output relay contacts of the protection device.
2.5.1 Trip Circuit Supervision Mechanism
The Trip Circuit Supervision function included in the MiCOM P111Enh relays is described below:
A logic input is programmed to the GLOBAL CONFIGURATION/CIRCUIT BREAKER/TC Supervision function. The logic input is associated to the label Trip Circ Supervis.. within the SETTING GROUPx/INPUT CONFIGURATION Gx menu. Then, this logic input is wired in the trip circuit according to one of the typical application diagrams shown in the following example.
When the TC Supervision function is set to Yes under the CIRCUIT BREAKER sub-menu, the relay checks continuously on trip circuit continuity whether the CB’s status is open or closed.
When the TC Supervision function is set to Yes-52A under the CIRCUIT BREAKER sub-menu, the relay checks continuously on trip circuit continuity in case when the CB’s status is closed only.
The TC Supervision function is enabled when the Protect.trip or Trip CB order output is not energized. The TC Supervision function is not enabled when the Protect.trip or Trip CB is energized.
A TCS 52 Fail and CB Alarm output function, TCS Supervision Alarm and CB Alarm LEDs function signal is generated if the logic input detects no voltage signal during a time longer than the settable timer tSUP (in GLOBAL CONFIGURATION/CIRCUIT BREAKER menu). See Chapter P111Enh/EN TD (Technical Data) for the settings.
As this function is disabled when the Protect.trip or Trip CB order output is energized, this function is suitable for use with the enabled relay latching logic.
The tSUP timer can be set according to the following table:

2.6 Commissioning
2.6.1 Maintenance Mode (Model A and E)
This menu allows the user to check the operation of the protection functions.
It is possible to set following Maintenance mode options (settings):
• “No” — Maintenance mode is disabled. All window cells below are hidden (Maintenance mode is the latest cell in COMMISIONING column)
• “Yes,outp.trips” — Maintenance mode is enabled. In this mode all test cells in COMMISIONING column are shown. During tests outputs are energized.
• “Yes,outp.block” — Maintenance mode is enabled and all test cells in COMMISIONING column are shown. In this mode, the high state of output functions are ignored (control of outputs are blocked).
This option allows the user to check the operation of the protection functions without actually sending any external command (Tripping or signalling).
Depends on the rear protocol selected in menu, transmission of information to SCADA is blocked (Modbus RTU) or sent (IEC 103) with additional information to know that P111Enh is in Maintenance mode (refer to Communication chapter and EN 60870-5-103 standard).
Changing of setting from “No” to “Yes,….” from the front panel activate this mode for 10 minutes only. After this time the option is automatically switched to “No”.
The selection of the maintenance mode is possible by logic input (the level), control command (rear or front port), or by front panel interface. The maintenance mode is terminated by:
• Low state of logic input assigned to Maintenance mode function,
• Control command which activate this mode (rear command or setting: “Yes,….”) and by turning off the power supply.
Note: Maintenance rear command is available in Modbus protocol only
Maintenance Mode 1: Yes,outp.trips
It is possible to assign the state of Maintenance Mode to programmable LEDs.
In “Yes,outp.block” case, all the output contacts are blocked, and no command can be issued to these contacts, even if a protection threshold associated with one of these output contacts has been crossed. (If a protection threshold is crossed, all associated LEDs will be ON, even the TRIP LED, if protection element is set to Trip).
If the Maintenance Mode is set in menu (“Yes,outp.trips” or “Yes,outp.block”) after 10 minutes this function returns automatically to Maintenance mode “No” (function disabled).
If the input assigned to Maintenance Mode is logical high the Maintenance Mode is active (without any time limitation) up to low state of the logical input.
2.6.2 Outputs test
This function is available after activation of Maintenance mode
The commissioning cells allow the user to check the external wiring to the relay’s output contacts. To do this, the user has only to set to 1 the desired output contact’s corresponding bit, and this will close the contact and allow the continuity of the wiring to be checked.

To execute the test, press OK key, press the or key to select 1: Apply test and confirm action by OK. The contact will be closed for the duration of the Contact Test Time pulse.
2.6.3 Functional test
This function is available after activation of Maintenance mode
The next commissioning cells allow the user to check the functional output configuration of the P111Enh. To do this, the user has only to select which protection element will be triggered, and this will close the contact assigned to this protection element and allow the continuity of the wiring to be checked. If the protection element is disabled there will be no action.
Functional Test 0: I>
In the cell below the end of the functional test can be configured:
Functional Test End 0: CB trip
The following options are possible:
— 0: CB trip – after triggering the functional test, the test is interrupted after trip command.
— 1: Time – the protection element will be triggered for the duration of the pulse time.
If the 1: Time option is selected it is necessary to set the pulse length:
Contact Test Time 001.00s
The next cell is used for functional test execution:
Functional Test CTRL: no operation
To execute this test, press the OK key, press the or key to select 1: Operate and confirm action by pressing OK. The contact will be closed for the duration of the Contact Test Time pulse.
NOTE: In Maintenance Mode P111Enh works with full functionality (ready to trip in a fault condition, even during functional test). During functional test of selected stage (for example tI>), P111Enh measures currents so the rest active stages (for example tI>>, tIN>, etc) work on the measured current from the field. Only the tested stage (for example tI>) sees test current: two times greater than tI> current setting value in all phases. After functional test of Thermal replica, the thermal value is set to 0%. After test, in the fault record all recorded current values are based on the currents measured in the field.
If Functional Test will be applied for protection element which is disabled there will be no any action done.

2.7 Circuit Breaker Control
The relay includes the following options for control of a single circuit breaker:
— Local tripping and closing, via the relay menu or function keys
— Local tripping and closing, via relay binary inputs
— Remote tripping and closing, using the relay communications
If a local/remote external selector switch is to be used, it is recommended that separate relay output contacts are assigned to remote circuit breaker control and protection trip. This enables the control outputs to be selected via a local/remote selector switch as shown in Figure 14.
Where this feature is not required or is connected to a P111Enh’s binary input, the same output contact(s) can be used for both protection (Protect.Trip output) and remote tripping (Trip CB order output).
Figure 14: Remote Control of Circuit Breaker
A manual trip will be permitted provided that the circuit breaker is initially closed. Likewise, a close command can only be issued if the CB is initially open. To confirm these states it will be necessary to use the breaker 52A (assigned to CB status 52A input(ABE)) and/or 52B (assigned to CB status 52B input (ABE)) contacts. Under these circumstances manual CB control will be possible, but the Auto-reclose function will not be available. Additionally, it will be not possible to see the CB status in the Control default cell.
Once a CB Close command is initiated the output contact (Close CB order) can be set to operate following a user-defined time-delay (Time-delay for Close setting in GLOBAL SETTINGS/CIRCUIT BREAKER menu). This would give personnel time to move safely away from the circuit breaker following the close command. This time-delay will apply to all manual CB Close commands.
P111Enh_EN_OP v1.3
Operation (OP) 5-44 MiCOM P111Enh
OP
The length of the trip or close control pulse can be set via the tOPen pulse min and tClose Pulse settings respectively (GLOBAL SETTINGS/CIRCUIT BREAKER menu). These should be set long enough to ensure the breaker has completed its open or close cycle before the pulse has elapsed.
Note: The manual trip and close commands are found in the default Control cell and the Close/Trip keys on the front panel.
If an attempt to close the breaker is being made, and a protection trip signal is generated, the protection trip command overrides the close command.
If CB FLT Ext.Sign (ABE) is assigned to a binary input this signal is checked before manual closing of the CB. This function uses the signal received at the relay’s binary input to confirm whether the breaker is capable of closing (sufficient circuit breaker energy for example). A user-settable time-delay, tCB FLT ext (ABE), is included for manual closure. If, following a close command, the CB does not signal a healthy condition before that timer elapses, then the relay will lockout and issue an alarm.
2.8 Real Time Clock Synchronization via Opto-Inputs (Model E)
In modern protective schemes it is often desirable to synchronize the relay’s real time clock so that events from different relays can be placed in chronological order. This can be done using the communication interface connected to the substation control system or via a binary input. Any of the available binary inputs on the P111Enh relay can be selected for synchronization. Pulsing this input will result in the real time clock snapping to the nearest minute. The recommended pulse duration is 20 ms to be repeated no more than once per minute. An example of the time synchronization function is shown.
Time of “Sync. Pulse” Corrected Time
19:47:00.000 to 19:47:29.999 19:47:00.000
19:47:30.000 to 19:47:59.999 19:48:00.000
Note: The above assumes a time format of hh:mm:ss
The input is configured in the SETTING GROUPx/INPUT CONFIGURATION Gx menu. The input must be assigned to the Time Synchr. Input (Model A and E).
2.9 Resetting of Latched LEDs and Outputs
How latched LEDs and outputs are reset is determined by the inputs assigned to the resetting of latched LED. Outputs can be reset via external inputs, by pressing the clear key on the P111Enh’s front panel if the LCD shows the default display or via the communication port.
The resetting configuration can be entered in the GLOBAL SETTINGS/LOC menu:
— LEDs Reset:
— 0: Manual only (via Inputs, HMI key, Remote Reset command)
— 1: Start protect. (Start of a protection element set to Trip)
— Ltchd Outp. Reset:
— 0: Manual only (via Inputs, HMI key, Remote Reset command)
— 1: Start protect. (Start of a protection element set to Trip)
The Manual only option prevents a close command from being issued without readout of the cause of trip by maintenance personnel. It reduces the risk to switch on to fault.
The Start protect option allows to signal the latest trip only: Start of any protection element set to trip the CB, reset all latched LEDs and show the default display.

2.10 Records
2.10.1 Fault Recorder
Each time any of the set thresholds are crossed, an instantaneous record is created and displayed in the RECORDS/INSTANTANEOUS RECORD menu (E). Information on the last five starts is available, with the duration of the signal.
The following information is displayed in the RECORDS/INSTANTANEOUS RECORD menu (E): time, date, origin (crossing of a current threshold or start of a protection element’s time-delay), and current values.
Each time any of the set protection elements trips (Protect.Trip output), a fault record is created and stored in memory. The fault record tags up to 20 faults and stores them in a non-volatile (FRAM) memory. This allows the operator to identify and analyze system failures. When the available memory space is exhausted, the new fault automatically overwrites the oldest fault.
The user can view the latest fault record in the RECORD/FAULT RECORDS menu, where the user can choose to display up to 20 stored records. These records are the fault flags, the fault measurements, etc. Also note that the time stamp displayed in the fault record itself will be more accurate than the corresponding time stamp given in the event record. This is due to the fact that events are logged some time after the actual fault is recorded.
The user can view event records either via the front panel interface, via the USB port (NABE), or remotely, via the rear EIA(RS)485 port (L – optional).
2.10.2 Alarm Recorder
Each time any of the set protection element issues an ALARM signal (Alarm output), an Alarm record is created and stored in memory. The fault record tags up to 5 faults and stores them in a non-volatile (FRAM) memory. This allows the operator to identify and analyze system failures. When the available memory space is exhausted, the new alarm automatically overwrites the oldest alarm.
The user can view the latest Alarm record in the RECORD/ALARM RECORDS menu, where he or she can choose to display up to 5 stored records. These records are the alarm flags, the alarm measurements, etc. Also note that the time stamp displayed in the Alarm record itself will be more accurate than the corresponding time stamp given in the event record..
2.10.3 Instantaneous Recorder (Model E)
Each time any of set thresholds are crossed, an instantaneous record is created and displayed in the RECORDS/INSTANTANEOUS RECORD menu. The last five starting records are available, with the duration of the signal.
The following information is displayed in the RECORDS/INSTANTANEOUS RECORD menu: number of starts, time, date, origin (crossing of a current threshold or start of a protection element’s time-delay), current values.
NOTE: Instantaneous Records is active if P111Enh is powered from the auxiliary voltage Vx.

2.11 Disturbance Recorder (Model A and E)
The integral disturbance recorder has a memory space specifically dedicated to the storage of disturbance records. Up to 3 seconds of disturbance recording can be stored. When the available memory space is exhausted, the new record automatically overwrites the oldest record.
The recorder stores actual samples that are taken at a rate of 16 samples per cycle.
Each disturbance record consists of analogue and digital channels. (Note that the relevant CT ratios for the analogue channels are also extracted to enable scaling to primary quantities).
The disturbance recorder is set in the GLOBAL SETTINGS/DISTURBANCE RECORDER menu.
The total disturbance recording time is 3 s but not more than 5 records are available.
Total number of records available in disturbance recorder is:
o One — for set Max Record Time from in range: 1.51s — 3s
o Two – for set Max Record Time from in range: 1.01s – 1.5s
o Three – for set Max Record Time from in range: 0.76s — 1s
o Four – for set Max Record Time from in range: 0.61s – 0.75s
o Five — for set Max Record Time from in range: 0.10s – 0.6s
Triggering of disturbance recording depends on the Disturb.Rec.Trig. configuration:
— 0: on Inst. – Start of a protection element set to Trip,
— 1: on Trip – Trip by a protection element followed by the Protect.Trip output.
If the 0: on Inst. option is selected the record consists of: Pre-fault time + duration of the «any Start» signal presence + Post-fault time.
If the 1: on Trip option is selected the record consists of: Pre-fault time + duration of the Trip signal presence (Protect.Trip function active) + Post-fault time.
The pre-fault time can be set in the cell: GLOBAL SETTINGS/DISTURBANCE RECORDER/Pre-Time. If the pre-fault time is set to 100 ms, recording starts 100 ms before the disturbance.
The post-fault time can be set in the cell: GLOBAL SETTINGS/DISTURBANCE RECORDER/Post Trip Time. If the post trip time is set to 100 ms, recording stops 100 ms after the trip signal.
2.12 Event Records (Model N, B, A and E)
The relay records and time-tags up to 200 events and stores them in a non-volatile (Fram) memory. This allows the system operator to analyze the sequence of events that has occurred within the relay after a particular power system condition, or switching sequence, etc. When the available space is exhausted, the new fault automatically overwrites the oldest fault.
The real time clock within the relay time-tags each event, with a resolution of 1 ms.
The user can view the event records either locally via the USB port (NABE), or remotely, via the rear EIA(RS)485 port (L – optional).

1. INTRODUCTION 1.1 Protection of Underground and Overhead Lines
The secure and reliable transmission and distribution of power within a network is heavily dependent upon the integrity of underground cables and overhead lines, which link the various sections of the network together. Therefore the associated protection system must also provide both secure and reliable operation.
The most common fault conditions on underground cables and overhead lines are short circuit faults. These faults may occur between the phase conductors but will most often involve one or more phase conductors being short-circuited to the earth.
Faults caused by short circuits require the fastest clearance times but these should still allow for suitable co-ordination with other downstream protection devices.
Fault sensitivity is an issue common to all voltage levels. For transmission systems, tower-footing resistance can be high. Also, high resistance faults might be prevalent where lines pass over sandy or rocky terrain. Fast and discriminative fault clearance is required in these conditions.
The effect of fault resistance is more pronounced on lower voltage systems, resulting in potentially lower fault currents, which in turn increases the difficulty in the detection of high resistance faults. In addition, many distribution systems use earthing arrangements designed to limit the passage of earth fault current.
Earthing methods as such as resistance, Petersen coil or neutral-insulation make the detection of earth faults arduous. Special protection equipment is often used to overcome these problems.
Nowadays, the supply continuity of power distribution is of paramount importance.
On overhead lines, most faults are transient or semi-permanent in nature.
In order to increase system availability, multi-shot auto-reclose cycles are commonly used in conjunction with instantaneous tripping elements. For permanent faults it is essential that only the faulted section of the system is isolated. High-speed, discriminative fault clearance is therefore a fundamental requirement of any protection scheme on a distribution system.
Power transformers are installed at all voltage levels and have their own specific requirements with regard to protection. In order to limit the damage incurred by a transformer under fault conditions, fast clearance of phase to phase and phase to earth faults on the windings is a primary requirement.
Damage to electrical plant equipment such as transformers, cables and lines may also be incurred by excessive loading conditions, which lead directly to overheating of the equipment and subsequent damage to insulation. To protect against such fault conditions, protective devices must also provide thermal protection.
Uncleared faults, arising either from the failure of the associated protection system or of the switchgear itself, must also be considered. The protection devices concerned should be fitted with logic dealing with breaker failure and the upstream relays must be able to provide adequate back-up protection for such fault conditions.
Other situations may arise on overhead lines, such as broken phase conductors. Traditionally, series faults have been difficult to detect.
With today’s numerical technology, it is now possible to design elements that are responsive to such unbalanced system conditions and to subsequently issue alarm and trip signals.
On large networks, time co-ordination of the overcurrent and earth fault protection relays can often lead to problematic grading situations or, as is often the case, excessive fault clearance times. Such problems can be overcome by relays operating in blocked overcurrent schemes.
Due to its dual powering featuer, the P111Enh can be used as back-up protection of HV/MV transformers.

2. APPLICATION OF INDIVIDUAL PROTECTION FUNCTIONS The following sections detail individual protection functions in addition to where and how they may be applied. Each section provides some worked examples on how the settings are applied to the relay.
Figure 1: P111Enh single-line functional diagram (all options included)
2.1 Earth and Phase Overcurrent Functions
MiCOM P111Enh relays provide definite and independent time-delayed overcurrent protection.
Each phase current and earth current input is associated with three stages.
The first and second timer stages can be set to definite time-delay or inverse time-delay using the IEC, IEEE, CO, RXIDG, BPN, RI and RECT curves. Their parameters are shown in the Technical Data chapter of this Technical Guide.
The third stages can be set as definite time-delay only.
Similarly, the earth fault elements has three different stages, that also can be set independently of the settings chosen for the phases.
The instantaneous stages are labeled “I>” for the first stage, “I>>” and “I>>>” for the second and third instantaneous stages respectively (“IN_1”, “IN_2” and “IN_3” (E) for earth fault elements).
The time-delayed stages are labeled “tI>” for the first stage, “tI>>” and “tI>>>” for the second and third time-delayed stages respectively (“tIN_1”, “tIN_2” and “tIN_3” (E) for the time-delayed earth fault stages).
The protection elements trip when the following conditions are realized:
— A phase current exceeds the set overcurrent threshold
— The relevant time-delay has elapsed
— The blocking logic (if used) is not activated.
The following diagrams show the functionality for each stage.

With: Max I> = [IA>] OR [IB>] OR [IC>]
Max I>> = [IA>>] OR [IB>>] OR [IC>>]
Max I>>> = [IA>>>] OR [IB>>>] OR [IC>>>]
Note: Model E has possibility to set 50/51 protection element for a one phase only (for example for phase A or phase B or phase C), so if this protection element is assigned to one phase only, MAX value is equal the current value in selected phase (for example: I> is configured Trip-Phase A (E) so Max I> = [IA>])
The logic associated with the earth fault stage is identical to the logic described above. The stages I> & tI>, I>> & tI>> and I>>> & tI>>> are respectively replaced by the stages IN_1 & tIN_1, IN_2 & tIN_2, IN_3 & tIN_3(E).
Thanks to the «Blocking Logic» function, it is possible to freeze the timer as long as the «Block Logic» signal is active.
As soon as the blocking “Block Logic» signal drops, if the overcurrent value is still over the set threshold, the time-delay resumes using the value prior to the activation of the blocking function as its new initial value. This allows faster clearance of the fault after resetting of the “Block Logic» signal.
2.1.1 Instantaneous function
As soon as a phase (or earth) timer stage starts running, the instantaneous output associated with that stage is activated. This output indicates that the protection element has detected a phase (or earth) fault and that the corresponding time-delay has started. This time-delay can be blocked via the associated «Block Logic» logic input. If this blocking input is activated by an output contact of a downstream relay, the logic that will lead to the trip command is then blocked only if the relay that is the closest to the fault can see and therefore eliminate the fault. This principle is known as «Blocking logic» or «Blocking». It is described in more detail in this document.
2.1.2 DMT timer stages
The three phase (earth) overcurrent stages can be assigned definite time-delays. The time to operate is equal to the set time-delay plus the time for the output contact to operate (typically about 30 ms, 20 ms for a current exceeding or equal to twice the threshold) and the time required to detect the overcurrent condition (maximum 20 ms at 50 Hz).
For DMT stages, a definite-time «tReset» reset timer is associated with the first phase o/c stage, and with the first and second earth fault stages.

2.1.3 IDMT timer stages
The first and the second phase (I>, I>>) and e/f (IN_1) overcurrent stages can be selected with an inverse maximum time (IDMT) characteristic.
The time-delay in relay operation is calculated with a mathematical formula that depends on the relay current and TMS (IEC and UK) or TD (IEEE and US) values.
There are twelve inverse time characteristics available:
• SI: Standard Inverse Time Characteristic (IEC/A)
• VI: Very Inverse Time Characteristic (IEC/B)
• EI: Extremely Inverse Time Characteristic (EC/C)
• LTI: Long Time Inverse Characteristic (IEC)
• STI: Short Time Inverse Characteristic (FR)
• RC: Rectifier Characteristic (UK)
• MI: Medium Inverse Time Characteristic (IEEE, IEC/D)
• VI: Very Inverse Time Characteristic (IEEE, IEC/E)
• EI: Extremely Inverse Time Characteristic (IEEE, IEC/F)
• CO2 P20: Short Time Inverse Characteristic (US)
• CO2 P40: Short Time Inverse Characteristic (US)
• CO8: Inverse Characteristic (US)
• RI: Electromechanical Inverse Characteristic
• BNP Time Charactristic (EDF)
• RXIDG Time Charactristic
The mathematical formulae and curves for the twelve Inverse Time characteristics available with the P111Enh are presented in chapter OP (“Operation”).
2.1.4 Reset timer
The first two phase overcurrent stages [I>/tI>, I>>/tI>>] and the first earth fault stage ([IN_1/tIN_2] have a reset timer.
The value that is set for this reset timer corresponds to the minimum time during which the current value needs to be lower than 95% of the phase (or earth) threshold before the corresponding phase (or earth) time-delay is reset.
Note: This rule does not apply when the protection element is triggered. When the protection element is triggered, the time-delay tI> (or tIN>) is immediately reset.
DMT stages have DMT reset timers only.
IDMT characteristics can be associated with either a DMT or an IDMT reset timer. This selection is made in the menu:
— phase current: SETTING GROUP x/PROTECTION Gx /[50/51] PHASE OC Gx /Reset Delay Type: 0:DMT or 1: IDMT
— earth current: SETTING GROUP x/PROTECTION Gx /50/51N] E/GND FAULT Gx/Reset Delay Type: 0:DMT or 1: IDMT

DMT Reset Timer
Type of timer associated with the first & second phase (50/51 only) stages DMT Reset Timer
DMT (see note below) 0 ms to 600 s
IDMT 0 ms to 600 s
For the first phase and earth overcurrent stages, the MiCOM P111Enh has a timer hold facility, DMT tReset, which can be set to a definite time value or to an inverse time characteristic. This may be useful in some applications, for example when grading with upstream electromechanical overcurrent relays which have inherent reset time-delays.
This timer hold facility is used to reduce fault clearance times and is also useful in situations where intermittent faults may be experienced. This can for example be the case on a plastic-insulated cable. In that case, the fault energy may cause the cable insulation to melt and reseal, thereby extinguishing the fault. This process repeats itself a couple of times giving a succession of fault current pulses, each of increasing duration with reducing intervals between the pulses, until the fault becomes permanent.
When the reset time of the overcurrent relay is instantaneous the relay will be repeatedly reset and unable to trip until the fault becomes permanent. By using the Timer Hold facility, the relay will integrate the fault current pulses, thereby reducing fault clearance time.
The MiCOM P111Enh’s reset timer DMT tReset can be found in the following menu cells:
• SETTING GROUP x/PROTECTION Gx /[50/51] PHASE OC Gx /DMT tReset for the phase.
• SETTING GROUP x/PROTECTION Gx /[50/51N] E/GND FAULT Gx /DMT tReset for the earth.
IDMT Reset Timer (IDMT Reset Characteristic)
This feature may be useful in certain applications, for example when grading with upstream electromechanical overcurrent relays, which have inherent reset time-delays. Setting the hold timer to a value other than zero, delays the resetting of the protection element timers for this period, thus allowing the element to behave similarly to an electromechanical relay.
Another possible situation where the timer hold facility may be used to reduce fault clearance times is where intermittent faults may be experienced. An example of this may occur in a plastic-insulated cable. In this application it is possible that the fault energy melts and reseals the cable insulation, thereby extinguishing the fault. This process repeats to give a succession of fault current pulses, each of increasing duration with reducing intervals between the pulses, until the fault becomes permanent.
When the reset time of the overcurrent relay is instantaneous, the relay will be repeatedly reset and unable to trip until the fault becomes permanent. By using the Timer Hold facility for IDMT characteristics the relay will integrate the fault current pulses, thereby reducing fault clearance time.
For IDMT it is possible to set the timer hold facility based on the following formulae:

2.1.5 Time-graded protection
Inverse definite minimum time relays are time graded in such a way that the relay closer to the fault operates faster than the upstream relays. This is referred to as relay co-ordination because if the relay nearest to the fault does not operate, the next relay will trip in a slightly longer time. The time grading steps are typically 400 ms, the operation times becoming progressively longer with each stage.
When difficulty is experienced in arranging the required time grading steps, the use of a blocked overcurrent scheme should be considered (described in § 2.14 of the Operation chapter, P111Enh/EN OP).
Note: The dynamic measurement range is typically 600 times the minimum setting.

2.1.6 Earth fault protection
Earth fault (E/F) current is measured on the e/f input.
Three stages are available: IN_1, IN_2 and IN_3 (E). The first stage has IDMT or DT characteristics. The types of characteristics are the same as for I> (refer to section 2.1.3).
2.1.7 Setting guidelines
When applying the overcurrent protection provided in the P111Enh relays, standard principles should be applied in calculating the necessary current and time settings for co-ordination The Network Protection and Automation Guide (NPAG) textbook offers further assistance. The example detailed below shows a typical setting calculation and describes how the settings are applied to the relay.
Assume the following parameters for a relay feeding an LV switchboard:
CT Ratio = 500 A/1 A
Full load current of circuit = 440 A
Slowest downstream protection = 100 A Fuse
The current setting employed on the P111Enh relay must account for both the maximum load current and the reset ratio of the relay itself:
I> must be greater than: (440 A/0.95)/500 A = 0.9263 In
I> must be greater than: 0.9263 In
For setting range 0.2-4 In step is 0.01 In, so the closest I> set value = 0.93 In.
A suitable time-delay characteristic can now be chosen. When coordinating with downstream fuses, the applied relay characteristic should be closely matched to the fuse characteristic. Therefore, assuming IDMT co-ordination is to be used, an IEC Extremely Inverse (EI) time characteristic would normally be chosen.
Finally, a suitable time multiplier setting (TMS) must be calculated and entered. .

InAAI ⋅==> 72.1100/172
Calculation of the required E/F settings The setting value of E/F overcurrent protection should be greater (with safety margin) than the charging currents flowing in the protected line to prevent an earth fault in other parts of the system tripping the relay. The value of the safety coefficient depends on the application and accuracy of obtained earth fault current value (typically: 1.5 to 2.5).
2.2 Transformer Magnetizing Inrush (Inrush Blocking) (Model A and E)
The inrush blocking function ensures protection stability during transformer energizing based on the presence of harmonic 2.
Either I>>/IN_2 or I>>>/IN_3 (E) can be used as high-set instantaneous elements. Their design is such that they do not respond to the DC transient component of the fault current. The principle of operation allows the current settings to be set down to 35% of the prospective peak inrush current that will be absorbed by a transformer when it is energized. As a first approximation, the peak inrush current is given by the converse of the per unit series reactance of the transformer.
As an alternative, inrush blocking can be applied. This is discussed in the next section.
In applications where the sensitivity of overcurrent thresholds need to be set below the prospective peak inrush current, the inrush blocking function can be used to block the overcurrent, earth fault and negative sequence overcurrent stages. During transformer inrush conditions, the second harmonic component of the inrush current may be as high as 70%. In practice, the second harmonic level may not be the same for all phases during an inrush and therefore the relay will issue an Inrush Blocking signal for any phase above the set threshold. A setting of 15% to 20% for the Inrush harmonic 2 ratio can be applied in most cases. Care must be taken that it is not set too high, as inrush blocking may not operate for low levels of second harmonic current which may result in the O/C element tripping during transformer energization. Similarly if it is set too low, inrush blocking may prevent tripping for some internal transformer faults with significant second harmonic current
2.2.1 Overview
The Inrush Blocking function measures the ratio of second to fundamental harmonic currents. It can be used as “blocking logic” for I>, I>>, I>>>, SOTF(ABE), IN_1, IN_2, IN_3 (E), I2> (E), Broken Conduct (E), in cases where the harmonic 2 ratio is higher than the set threshold. Indeed, inrush blocking functions will reset selected protection starts.
Two options are available (GLOBAL SETTINGS/INRUSH BLOCKING menu):
— 1: Yes
— 2: Closing
If 1: Yes is selected, the minimum duration of the overcurrent stage inhibition (T Inrush Reset) can be also set. This value depends on the transformer power transient inrush duration: between 0.1 second (for a 100 kVA transformer) to 1.0 second (for a larger unit). It is used to avoid any maloperation during a fixed time period in case of too sensitive a setting. For example, this option is recommended for incoming feeders where the inrush current is caused by a transformer connected to an outgoing line. However, using the second harmonic can increase the tripping time in case of a fault, especially with DC component included. This option can also be used if the CB contacts are not assigned to any P111Enh inputs (no information about CB closing).
P111Enh_EN_AP_A11 v1.3
Application Notes (AP) 6-14 MiCOM P111Enh
AP
If 2: Closing is selected, the protection element block is active after the CB closes until Unblock Inrush Time elapses (this can be also set in the GLOBAL SETTINGS/INRUSH BLOCKING menu column). If 1: Closing is selected, the minimum duration of the overcurrent stage inhibition (T Inrush Reset) can be also set (see above: 1: Yes). This option can increase protection reliability, because inrush blocking is limited to cases where inrush current can appear (closing of CB). Therefore it can be used on outgoing lines with transformers. Note that for incoming feeders the inrush current can be also present when CB is closed and an outgoing line with a transformer is closing. In such a case the CB status of the incoming feeder is not changed but Inrush current can trip protection element. The 2: Closing option is not recommended for such an application.
2.2.2 Operation
For each of the three phases currents (IA, IB, IC), the harmonic restraint function compares the ratio of harmonic 2 to the fundamental with the set ratio (Harmonic 2 / Fundamental settable from 10 % to 50 % in steps of 1%).
The minimum fundamental current value required for operation of the Inrush Blocking function is 0.2 In, and there is no upper limit to disable this feature. However, in transformer protection, this Inrush Blocking feature shall not control the high set overcurrent stage; this enables detection of all high current faults without inrush blocking.
Inrush blocking configuration offers two options:
— 1: Yes — The Inrush Blocking function will block the selected protection stages every time inrush conditions occur on the line (Ratio of measured 2nd Harmonics > Inrush H2 set ratio), and will remain active at least for the duration of T Inrush Reset. The tReset timer defines the minimum duration of overcurrent protection inhibition (0-200 s, settable). This timer starts as soon as an inrush current threshold picks up:
If the inrush condition lasts less than the set value for T Inrush Reset., the selected overcurrent function will remain inhibited for the duration of tReset.
If the inrush condition lasts longer than the set value for T Inrush Reset., the selected overcurrent function will remain inhibited as long as the inrush condition is present.
— 2: Closing — The Inrush Blocking function will block the selected protection stages every time the CB closes (P111Enh closing command) until Unblock Inrush Time has elapsed and as long as the inrush conditions are present on the line (Ratio of measured 2nd Harmonics > Inrush H2 set ratio). If 1: Closing is selected, the minimum duration of the overcurrent stage inhibition (T Inrush Reset) can be also set (see above: 1: Yes).
The operating Inrush current (2nd Harmonic Ratio) is settable from 10% to 50% of the fundamental current.
Under inrush conditions, the following selectable protection stages can be blocked: I>, I>>, I>>>, SOTF (ABE), IN_1, IN_2, IN_3 (E), I2>(E), Broken Conduct (E), if they are set to 3: Trip-Inrush Bl.
Note: Inrush Blocking in P111Enh relays is not phase-selective. If an inrush condition occurs on any phase, the selected protection stages will be blocked in all 3 phases.

2.3 Busbar Protection on Radial Systems
The use of non-directional overcurrent relays to protect a busbar is based on the following hypotheses:
— The network is a radial system,
— The incoming and outgoing feeders are clearly defined, the incoming feeders always being considered as suppliers of energy and outgoing feeders as loads.
Under these circumstances, the busbar is effectively protected using the interlocking principle (Figure 4).
Figure 4: Blocked Overcurrent for Busbar Protection
The instantaneous overcurrent signals of the protection relays on the feeders are grouped together and wired to the «Blocking logic» logic input of the relay protecting the incoming feeder. The blocking function is programmed to inhibit either the first or first two stages. The third I>>> stage will operate at a high value (> 10 In) with a short time-delay (< 60 ms).
If a fault appears on the system, the relay protecting the associated feeder will immediately (in less than 30 ms) send a blocking command to the relay protecting the incoming feeder. After the fault has been cleared (by opening the circuit breaker), the blocking command is withdrawn and the relay protecting the incoming feeder is unblocked. As the fault current is no longer present, the timer is reset.
If a fault appears on the busbar, the fault current exceeds by far the value of the third threshold (I>>>). As this third stage is not blocked by the blocking logic of the relays protecting the incoming feeders, the trip command is sent in less than 60 ms and the busbar is isolated.

2.4 Blocking Logic Function (Blocked Overcurrent Protection) (Model A, B and E)
This type of protection can be applied to radial feeder circuits where there is little or no back feed. For parallel feeders, ring circuits or where there can be a back feed from generators, directional relays should be considered.
The blocking logic function allows the upstream IDMT relay to be blocked by the start output of a downstream relay that has detected the presence of a fault current above its threshold. Thus both upstream and downstream relays can have the same current and time settings, and the blocking feature will automatically provide grading. If the CB failure protection is active, the blocking command on the upstream relay will be removed if the down-stream circuit breaker fails to trip.
Thus for a fault downstream from relay C, the start output from relay C will prevent relay B from operating and the start output of relay B will prevent relay A from operating. Therefore all 3 relays could have the same timer and current settings and grading would be obtained by the blocking signal received from a relay closer to the fault. This gives a constant, close time grading, but there will be no back-up protection in the event of pilot wires being short-circuited.
In practice it is recommended to set the upstream relay to a value that is 10% higher than the downstream relay setting. This ensures that the downstream relay successfully blocks the upstream relay when required.
Figure 5: Blocking Logic
The «Blocking Logic» functions are assigned in the SETTING GROUP x/ INPUT CONFIGURATION Gx/ menu. Every protection element can be assigned a blocking function: Block.tI>, Block.tI>>, Block.tI>>>, Block.tSOTF, Block.tIN_1, Block.tIN_2, Block.tIN_3 (E), Block.tI2>(E), Block.tBrkn Cond (E), Block.Itherm (NABE), Block.AUX1 (NABE), Block.AUX2 (NABE), Block.AUX3 (NABE), Block.tCB Fail, Block.[79] (E).
MiCOM P111Enh relays have separate blocking functions, which can be used to block every protection element, for example: Earth fault and phase overcurrent stages.

2.5 Protection of Silicon Rectifiers
Figure 6: Protection of silicon rectifiers
Figure 7: Matching curve to load and thermal limit of rectifier
The rectifier protection feature is based upon the inverse time/current characteristic as used in the MCTD01 (Silicon Rectifier Protection Relay) and the above diagrams show a typical application.
Rectifier protection differs from the more traditional overcurrent applications in that many rectifiers can withstand relatively long overload periods without damage, typically 150% for 2 hours and 300% for 1 min.
The threshold I> should typically be set to 110% of the maximum allowable continuous load of the rectifier. The relay issues start indications when the setting of I> has been exceeded, but this is of no consequence, as this function is not used in this application. The rectifier curve should be selected as it allows for relatively long overloads even with I> set to 110%.

Typical settings for the TMS factor are:
Light industrial service TMS = 0.02
Medium duty service TMS = 0.1
Heavy duty traction TMS = 0.8
The high set threshold is typically set to 8 times the rated current as this ensures that HV AC protection will discriminate with faults covered by LV protection. However, it has been known for the high set threshold to be set to 4 or 5 times the rated current where there is more confidence in the AC protection device. Use of the thermal element to provide protection between 70% and 160% of the rated current could enhance protection. It is also common practice to provide restricted earth fault protection for the transformer feeding the rectifier.

2.6 Back-up Scheme using “Selective Transfer Tripping”
In this application, the relay protecting the incoming feeder can trip the circuit breaker of the faulty feeder via the watchdog contact of the relay protecting the faulty feeder.
Figure 8 illustrates this example:
Figure 8: Example of a back-up scheme using «selective transfer tripping»
Thus, a fault occurring on a feeder can be cleared by tripping the circuit breaker of the faulty feeder even if the relay protecting this feeder has failed to operate. Without this function, the fault would normally be cleared by the opening of the circuit breaker of the incoming feeder. This would lead to total disconnection of the affected busbar.
The relay protecting the incoming feeder has two time-delayed outputs available (among others):
• 3rd stage: tI>>> time-delay, at 60 ms (active stage for the high phase current faults).
• 2nd stage: tI>> time-delay, selectively longer than the third stage, i.e. 360 ms.
The output contact associated with the 2nd stage is wired in series with the watchdog contact of the downstream relays, so that it can activate the trip coil of the circuit breakers of the feeders. Regarding the output contact associated with the 2nd and 3rd stages, this contact is directly wired to the trip coil of the incoming feeder’s circuit breaker.
Case n°1 → all relays operate normally:
In this case, the watchdog contacts of all the relays are open.
Thus, for a phase fault on the busbar, stage tI>> or tI>>> of the P111Enh located on the incoming feeder will clear the fault.
For a phase fault on one of the feeder, the stages tI>> and tI>>> of the relay located on the incoming feeder being selectively set to higher values than the ones set for the phase o/c stages of downstream relays, the fault shall be cleared selectively by the relay of the faulty feeder (selectivity between the relay of the incoming feeder and relays of the outgoing feeders is ensured thanks to intervals of selectivity correctly chosen, or thanks to a suitable blocking scheme).

Case n°2 → the relay supervising one of the feeders is faulty:
In this case, the watchdog contact of that relay is closed.
Thus, for a phase fault on the busbar, stages tI>> and tI>>> activate their associated output contacts. However, stage tI>> will clear the fault as its threshold has been set to a lower value than that of stage tI>>>.
For a phase fault on one of the ‘healthy’ feeders, stages tI>> and tI>>> of the relay located on the incoming feeder being selectively set to higher threshold values than the ones set for the phase o/c stages of the downstream relays, the fault shall be cleared selectively by the relay of the faulty feeder (selectivity between the relay of the incoming feeder and relays of the outgoing feeders is ensured thanks to intervals of selectivity correctly chosen or to a suitable blocking scheme).
For a phase fault on the feeder of the failed relay, the stage tI>> of the relay located on the incoming feeder operates via the watchdog contact of the faulty relay on the trip coil of the circuit breaker of the faulty feeder. This stage being selectively set to a value lower than the stage tI>>> (which operates directly on the coil of the incoming feeder circuit breaker), the fault is therefore selectively cleared.

2.7 Remote Stand-By Protection Scheme
MiCOM P111Enh relays can be used as back-up for HV distance protection devices (Figure 9). Depending on the type of selectivity required, the P111Enh’s 51/51N element needs to be time-delayed either as definite time or as inverse time. The time-delay tI>/tIN> is set to a value that is compatible with stages Z2 or Z3 (2nd and 3rd distance protection zones).

The Watchdog contact of the distance protection (on a numerical protection unit) can be wired to a MiCOM P111Enh relay to optimize the trip time.

2.8 1 ½ Breaker Scheme
For HV/EHV substations with 1½ circuit breaker arrangements (Figure 10), the zone between the two circuit breakers and the switch section must be protected with a standard ANSI 50 protection device.
The tripping time is an essential criterion to be considered when choosing this protection device. MiCOM P111Enh relays are perfectly suited for this application. The time-delay of the first stage (tI>) is set to a low value (typically 100 ms above the circuit breaker failure time). This will allow the relay to be blocked by the close contact of the associated switch.

2.9 Thermal Overload Protection (Model N, A, B, E)
Thermal overload protection can be applied to prevent damages to the equipment of the electrical plant when operating at temperatures that are above the values designed for maximum withstand. A prolonged overloading causes excessive heating, which may result in premature deterioration of the insulation, or in extreme cases, insulation failure.
MiCOM P111Enh relays incorporate a current-based thermal replica, using load current to reproduce the heating and cooling of the equipment to be protected. The thermal overload protection element can be set with both alarm and trip stages.
Heating within any plant equipment, such as cables or transformers, is of resistive type (I²R x t). Thus, the quantity of heat generated is directly proportional to the current squared (I²). The thermal time characteristic used in the relay is based on current squared, integrated over time.
MiCOM P111Enh relays automatically use the highest phase current as input information for the thermal model.
The equipment is designed to operate continuously at a temperature corresponding to its full load rating, where the generated heat is balanced by the heat dissipated through radiation etc. Over-temperature conditions therefore occur when currents in excess of the rating are allowed to flow for a certain period of time. It can be shown that temperatures during heating follow exponential time constants and a similar exponential decrease of temperature occurs during cooling.
In order to apply this protection element, the thermal time constant (Te) of the plant equipment to be protected is therefore required.
A thermal time constant for cooling (Tr) is available for motor protection applications.
The following sections will show that different plant items possess different thermal characteristics, due to the nature of their construction.

The tripping time varies depending on the load current carried before application of the overload, i.e. whether the overload was applied from “hot” or “cold”.

2.10 Cold Load Pick-Up
The Cold Load Pick-up feature allows selected settings of MiCOM P111Enh relays to be changed to react to temporary overload conditions that may occur during cold starts. This condition may happen by switching on large heating loads after a sufficient cooling period, or loads that draw high initial starting currents.
When a feeder is energized, the current levels that flow for a period of time following energizing may differ greatly from the normal load levels. Consequently, overcurrent settings that have been applied to give short circuit protection may not be suitable during this period.
The Cold Load Pick-up (CLPU) logic raises the settings of selected stages for a set duration (tCL). This allows the protection settings to be set closer to the load profile. Cold load pick-up cannot restart until the end of tCL duration. The CLPU logic provides stability, without compromising protection performance during starting.
The CLP can be started by a digital logic Input Cold Load PU (Cold Load PU? 1: Cur+Input or Cold Load PU? 2: Input (ABE)) which can be assigned to 52a CB status or by current stages logic (Cold Load PU? 1: Cur+Input). If the Cold Load PU logic has to be triggered by current criteria only, Cold Load PU Input (ABE) function must not be configured to any digital input. Typically Cold Load PU (ABE) binary Input is wired to 52A CB status. If this function is configured to selected input, both criteria will work in parallel way.
The following diagram shows the logic start for CLPU:
Figure 11: Cold Load Pick-Up Logic
2.10.1 Example of Application for Earth Fault Protection Applied to Transformers
Where an earth fault relay is residually connected on the primary side of a delta-star transformer, no time-delay is required for co-ordination purposes, due to the presence of the delta winding. However, a nominal time-delay or stabilizing resistor is recommended, to ensure transient stability during transformer energizing.
The CLPU logic may be used in a similar manner to that previously described for the motor application.
This method will not provide stability in the event of asymmetric CT saturation (as a result of an unbalanced fault condition). In this case, use a stabilizing resistor.

2.11 Switch On To Fault / Trip On Reclose Protection (Model A, B, E)
2.11.1 General
In some feeder applications, fast tripping may be required if a fault is still present on the feeder after the reclosure of the circuit breaker (Close on to fault).
Some faults may not be cleared after a reclose due to the fact that the conditions that led to the fault have not been removed from the feeder after a reclosing cycle or a manual trip, or due to earthing clamps left on after a maintenance visit. In these cases, it may be desirable to clear the fault more quickly, rather than wait for the DMT or IDMT trip time-delay associated with the involved protection to elapse.
In the case of a CB being manually closed, a switch on to an existing fault may occur. This situation is particularly critical because the overcurrent protection element would not clear the fault until the set time-delay has elapsed. It is then desirable to clear the fault as fast as possible.
Enabling and setting the SOTF (Switch On To Fault) function can be done under the SETTING GROUP x/PROTECTION Gx/SOTF submenu.
Crossing of SOTF threshold will initiate the SOTF function.
2.11.2 SOTF description
The following signals can activate the SOTF function:
— closing by Input (Manual Close Input),
— manual closing controlled by the HMI, (Close key order),
— front panel communication control (HMI order),
— rear communication control (Rear Com order),
The diagram below illustrates this functionality.

Once this timer (52 Ublock.SOTF Time) is active and SOTF thresholds have been crossed, the tSOTF settable time-delay starts. This settable time-delay is particularly useful in applications where fault selectivity in stages two or three is required.
This time-delay (tSOTF) is also useful in cases where serious transients may be present, where the three poles of the CB do not all close at the same time and in cases where the CB may not close instantaneously.
tSOTF can also be considered as a trip time-delay that substitutes itself to the trip time-delay associated with the crossed threshold so that the tripping time is accelerated.
If a trip due to switch on to fault occurs during the reclaim time of the ARC, the trip will be final and the ARC will be locked.
If the SOTF stage is reset before the settable time-delay tSOTF elapses, the SOTF function is reset.

2.12 LOCAL / REMOTE MODE (Model A and E)
2.12.1 General
The goal of this feature is to make it possible to block commands sent remotely through communication networks (such as setting parameters, control commands, etc.), so as to prevent any accidents or maloperation during maintenance work performed on site.
A digital input labeled “Local CTRL mode” is assigned to this feature. In Local mode, only the synchronizing time signal is allowed.
The local mode can also be set in default CTRL mode cell. The Local/Remote mode state is displayed in this cell.
2.12.2 Setting
The Remote Mode state can be set in the GLOBAL SETTINGS/CIRCUIT BREAKER/ Remote CTRL Mode cell:
— 0: Remote only – Local control via an input or/and the HMI or/and the Close/Trip key are blocked.
— 1: Remote + LOC – Local and Remote control are permitted.
Note: The auto-recloser is not blocked via the Local/Remote Mode.
When the “Local” input is energized, all remote commands are blocked. When the “Local” input is de-energized, remote control commands are accepted.
If local/remote switching has to be done outside of the P111Enh, the output configuration can be as follows (Figure 13):
— the protection trip is assigned to the Prot.Trip pulse output,
— the remote close command is assigned to the Close CB Order output,
— the remote trip command is assigned to the Trip CB Order output.

2.13 Selective scheme logic (Model E)
The following figure describes the use of non-cascade protection schemes using the start contacts from downstream relays to block operation of upstream relays.
In the case of Selective Overcurrent Logic (SOL), the start contacts are used to increase the time-delays of upstream relays, instead of blocking them. This provides an alternative approach to achieving a non-cascade type of overcurrent scheme. It may be more familiar to some utilities than the blocked overcurrent arrangement.
Figure 15: TYPICAL SCHEME LOGIC
The SOL function temporarily increases the time-delay settings of the second and third stages of phase overcurrent, derived and measured earth fault and sensitive earth fault protection elements. This logic is initiated by energizing the appropriate logic input (SEL1 or SEL2) as selected in SETTING GROUP x/INPUTS CONFIGURATION Gx menu.
To allow time for a start contact to initiate a change of setting, the time settings of the second and third stages should include a nominal delay. Guidelines for minimum time settings are identical to those given for blocked overcurrent schemes.
The tSel1 and tSel2 timers can be independently set from 0 to 200 s (SETTING GROUP x/PROTECTION Gx/LOGIC SELECT. Gx menu).

— Trip CB with latching up to signaling reset (Protect.Trip, Prot.Trip pulse, Disturbance and Fault Recorder, TRIP LED and FLAG)
— Load Shedding triggered via AUX input (Trip CB Order), tAUX is time-delay for trip,
— Auto-reclose after Load Shedding triggered via AUX input (high level); tAUX is time-delay for close (Close CB Order),
— Auto-reclose after Load Shedding triggered via AUX input (low level); tAUX is time-delay for close (Close CB Order),
For more details about: Trip CB, Alarm signal, Trip with Inrush blocking, Trip CB with latching refer to the Operation Chapter (P111Enh/EN OP)
AUX and tAUX signal can be assigned to LEDs or outputs.

2.15 Setting Group Selection
MiCOM P111Enh relays have two protection setting groups called PROTECTION G1 and PROTECTION G2. Only a one group is active at any time.
If a group is used in an application it is possible to remove the other group from the menu in order to simplify the setting procedure. If one group only is chosen the relay uses Group 1 even if the other parameters are set to Group 2 (Inputs, Menu, Remote Group Setting).
The selection of the number of groups is done at GLOBAL SETTINGS/SETTING GROUP SELECT/ Number of Groups: 1: One Group or 2: Two Groups.
If 1: One Group is selected, the SETTING GROUP 2 column and the setting group cell are hidden in menu.
Switching between the groups can be done via:
— a selected binary input (ABE) assigned to the Setting Group 2 logic input (SETTING GROUP x/INPUTS CONFIGURATION Gx submenu),
— the relay front panel interface (GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group: 1: Group1 or 2: Group2),
— through the communications port (refer to Mapping Database for detailed information).
Switching between setting groups can be done even while a protection function is active (no timers are resetting).
The user can check which one of the setting groups is active looking in the OP PARAMETERS menu: Active Set Group cell.
The user can also assign the active group (Setting Group x function) to an output relay (SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx) or to an LED (SETTING GROUP x/LEDs CONFIGURATION G1).
Setting group change via a digital input
It is possible to change the setting group by energizing a digital input (ABE) (on level).
If the setting group switchover is done via a binary input (ABE), the change from Group 1 to Group 2 is executed after the set time-delay: t Change Setting G1->G2 (GLOBAL SETTINGS/SETTING GROUP SELECT) (ABE). The switch from Group 2 back to Group 1 is instantaneous.
Switch between Active Groups via a Binary Input (ABE)
When powering up the relay, the selected group (Group 1 or Group 2) corresponds to the state of the logic input assigned to Setting Group 2. This means:
A – Reverse Inp.Logic = 0 and Setting Group 2 = 1 (SETTING GROUP x/INPUTS CONFIGURATION Gx submenu),
If the programmed logic input starts being supplied with +V, then after the t Change Setting G1->G2 time-delay the active group will be G2. If the programmed logic input is not supplied with +V, then the active group will be G1.
B – Reverse Inp.Logic = 1 and Setting Group 2 = 1 (SETTING GROUP x/INPUTS CONFIGURATION Gx submenu),
If the programmed logic input is supplied with +V, then the active group will be G1. If the programmed logic input stops being supplied with +V, then after the t Change Setting G1->G2 time-delay the active group will be G2.
Application Notes
P111Enh_EN_AP v1.3 MiCOM P111Enh (AP) 6-37
AP
Notes: 1. Binary Input configuration is associated with both Setting Groups, so that if in a Setting Group the selected binary input is assigned to Setting Group 2, in the other group it must be set to Setting Group 2 as well, otherwise no switch will occur.
2. If the P111Enh is powering up (from the currents or the auxiliary voltage) and Group 2 is selected via a binary input, the t Change Setting G1->G2 time-delay is ignored (changing to setting group 2 is instantaneous – without time-delay).
3. The setting group switch is based on the level of the binary input. So as long as Setting Group 2’s logic signal is high, the P111Enh uses Setting Group 2.
Switch between Active Groups via the Menu or a Remote Command (RS485, USB)
By using the relay front panel interface it is possible to change the active setting group: 1: Group1 or 2: Group2 (menu cell: GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group).
Above menu cell is common for changing from panel interface and via remote command (RS485 or USB).
It means that if the GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group menu cell is set to 1: Group1 and the remote setting group 2 command is executed, the value of menu cell: GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group will be changed to 2: Group2 value (Active group: 2).
Setting group 1 will be applied if:
— 1: Group1 is set in the GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group menu cell from the relay’s front panel interface, or
— the remote setting group 1 command is executed. The value of the GLOBAL SETTINGS/SETTING GROUP SELECT/ Setting Group menu cell will then be changed to 1: Group1.
WARNING: If the digital input has been assigned to the setting group change, it is not possible to change the setting group via remote communications. If changing via Menu or RS485 is required ensure that no input is assigned to Setting Group 2.
Priority
The detailed logic table for setting group selection is shown below:
Binary Input Setting Group 2 (ABE)
Front Panel and
Remote Setting Active Group
Not configured G1 G1 Not configured G2 G2
G1 G1 G1 G1 G2 G1 G2 G1 G2 G2 G2 G2
Note: If a setting group change initiated by a remote command has not been effected due of priority settings, that command is ignored (not recorded in the P111Enh’s logic for the future, when priority settings allow changing).
It is possible to assign an Active Group state to an output contact by setting the output contact to the Setting Group x output (SETTING GROUP x/OUTPUT RELAYS CONFIGURATION Gx.
If Active Group signaling is required, some LEDs should be assigned to the Setting Group x function (SETTING GROUP x/LEDs CONFIGURATION Gx).

2.16 Maintenance Mode (Model A and E)
This menu allows the user to check the operation of the protection functions.
It is possible to set following Maintenance mode options (settings):
• “No” — Maintenance mode is disabled. All window cells below are hidden (Maintenance mode is the latest cell in COMMISIONING column)
• “Yes,outp.trips” — Maintenance mode is enabled. In this mode all test cells in COMMISIONING column are shown. During tests outputs are energized.
• “Yes,outp.block” — Maintenance mode is enabled and all test cells in COMMISIONING column are shown. In this mode, the high state of output functions are ignored (control of outputs are blocked).
This option allows the user to check the operation of the protection functions without actually sending any external command (Tripping or signalling).
Depends on the rear protocol selected in menu, transmission of information to SCADA is blocked (Modbus RTU) or sent (IEC 103) with additional information to know that P111Enh is in Maintenance mode (refer to Communication chapter and EN 60870-5-103 standard).
Changing of setting from “No” to “Yes,….” from the front panel activate this mode for 5 minutes only. After this time the option is automatically switched to “No”.
The selection of the maintenance mode is possible by logic input (the level), control command (rear or front port), or by front panel interface. The maintenance mode is terminated by:
• Low state of logic input assigned to Maintenance mode function,
• Control command which activate this mode (rear command or setting: “Yes,….”) and by turning off the power supply.
Note: Maintenance rear command is available in Modbus protocol only
When this menu is activated (set to: “Yes,outp.trips” or “Yes,outp.block”), the Alarm led is lit. Additionally it is possible to configure Maintenance Mode to programmable LED.
In “Yes,outp.block” case, all the output contacts are blocked, and no command can be issued to these contacts, even if a protection threshold associated with one of these output contacts has been crossed. (If a protection threshold is crossed, all associated LEDs will be ON, even the TRIP LED, if protection element is set to Trip).

2.17 Negative Sequence Overcurrent Protection (Model E)
In traditional phase overcurrent protection schemes, overcurrent thresholds must be set above the maximum load current levels. This limits sensitivity of the relay. Most protection schemes also use an earth fault element based on residual current, which improves sensitivity for earth faults. However, it can happen that some faults occur and stay undetected by such schemes.
Any unbalanced fault condition will produce negative sequence current. Thus, a negative phase sequence overcurrent element can detect both phase-to-phase and phase-to-earth faults.
This section describes how negative phase sequence overcurrent protection may be applied in conjunction with standard overcurrent and earth fault protection in order to solve some application problems.
• Negative phase sequence overcurrent protection is more sensitive to resistive phase-to-phase faults than phase overcurrent elements, which may not operate.
• In some applications, an earth fault relay may not be able to detect a residual current because of the configuration of the network. For example, an earth fault relay connected on the delta side of a delta-star transformer is unable to detect earth faults on the star side. However, negative sequence current will be present on both sides of the transformer in any fault condition, independently of the transformer configuration. Therefore, negative phase sequence overcurrent element may be used to provide time-delayed back-up protection for any uncleared asymmetrical faults.
• Where fuses are used to protect motors on rotating machines, a blown fuse produces a large amount of negative sequence current. This is a dangerous condition for the machine because negative phase sequence current generates overheating. Then, a negative phase sequence overcurrent element may be used to back-up motor protection relays.
• It may also be required to trigger an alarm to announce the presence of negative phase sequence currents in the system. Operators are then prompted to investigate the cause of the unbalance.
The negative phase sequence overcurrent elements have a current pick up setting, I2>, and can be time-delayed using configurable timer tI2>.
I2> stages can be set under the SETTING GROUP x/PROTECTION G1 (2)/[46] NEGATIVE SEQ. O/C menu column.
The current pick-up stage I2> must be set to a value that is higher than the normal negative phase sequence current because of the normal unbalance conditions on the network. This can be done practically during the commissioning, using the MEASUREMENTS menu of the relay to display the negative phase sequence current value. Then, this value has to be increased by 20%.
Where negative phase sequence element is used to clear particular cases of uncleared asymmetric faults, the stage setting have to be calculated based on a fault analysis of that particular system, due to the complexities involved. However, to ensure that the protection element will operate, the current pick-up value has to be set to approximately 20% below the lowest calculated negative phase sequence fault current for a specific remote fault.
It is essential to set correctly the time-delay associated with this function. It should also be noted that this element is used primarily as a back-up protection to other protective devices or to provide an alarm. Therefore, this function is usually set with a long time-delay.
Care must be made to ensure that the time-delay is set above the operating time of any other protection device (at minimum fault level) present on the system and that may react to unbalanced faults, such as:
• Phase overcurrent elements
• Earth fault elements
• Broken conductor elements

The tI2> time-delay associated with the I2> stage can be set under the menu SETTING GROUP x/PROTECTION G1 (2)/[46] NEGATIVE SEQ. O/C.
2.18 Broken Conductor Detection (Model E)
Most of the faults that affect a power system occur between one phase and the earth or between two phases and the earth. These faults are shunt faults and are caused by lightning discharges and other overvoltages generating flashovers. They may also arise from birds on overhead lines or mechanical damage on underground cables, etc.
Such faults lead the current to increase appreciably and therefore they can easily be detected in most applications. Open circuit faults are a different type of faults that can happen in electrical networks. These faults can be caused by broken conductors, blown fuses or maloperation of a pole of a circuit-breaker.
Series faults will not lead to an increase in phase current and therefore they cannot easily be detected by common overcurrent relays. However, this type of fault produces an unbalance that creates negative phase sequence current, which can be detected.
The use of negative phase sequence overcurrent is then recommended to detect such faulty conditions. However, on lightly loaded lines, the value of the negative sequence current caused by a faulty condition may be very close to, or even inferior, to the full load steady state unbalance generated by CT errors, load unbalances, etc. As a consequence, a negative sequence protection element would not work for low level of loads.
As a solution, the MiCOM P111Enh have a protection element that measures the ratio between the negative and the positive phase sequence current (I2/I1). By using this ratio rather than only the measured I2, the relay will be able to detect a fault condition independently of the load level on the power system, since the ratio remains approximately constant whatever the variations in load current. It is then possible to have a more sensitive setting.
Note: The Broken Conductor function is inhibited if the value of the current flowing in each of the three phases is below Brkn Cond I< block undercurrent threshold (factory setting: 10% of the nominal current).
Setting Guidelines
On single point earthed power systems, there is a low zero sequence current flow and the ratio Is2/Is1 that flows is close to 100%. On power systems with multiple earthing, (assuming that the impedances in each sequence system are equals), the ratio I2/I1 will be equal to 50%.
It is possible to calculate the ratio I2/I1 corresponding to various system impedances, according to the following equations:
I1F = Eg(Z2+Z0)Z1Z2+Z1Z0+Z2Z0
I2F =
–EgZ0Z1Z2+Z1Z0+Z2Z0
Where:
Eg = Power System Voltage Z0 = Zero sequence impedance Z1 = Positive sequence impedance Z2 = Negative sequence impedance
Therefore:
I2FI1F
=
As a consequence, for an open circuit in a particular part of the system, I2/I1 can be determined from the ratio between the zero sequence and the negative sequence
Z0Z0+Z2

AP
impedance. It must be noted however that this ratio may vary depending on the location of the fault. It is therefore desirable to apply a setting that is as sensitive as possible. Practically, the levels of standing negative phase sequence current present on the system guide the choice of this minimum setting. A system study or the use of the relay’s measurement data during commissioning are two ways to determine this minimum setting. If the latter method is chosen, it is important to record measurements during maximum load conditions, to ensure that all single-phase loads are taken into account.
A time-delay (tBCond) is necessary to ensure co-ordination with other protective devices.
2.18.1 Setting Example
The following information comes from a the relay commissioning report;
IFLC = 500 A
I2= 50 A
Then:
I2/I1 = 50/500 = 0.1
To include some margin and tolerate load variations, it is typical to set this value 200% above this result: Therefore, RATIO I2/I1 = 20%
Set tBCond to 60 s to allow short circuits to be cleared by time-delayed protection elements.

2.19 Description and Setting Guide of the Auto-Reclose Function (Model E)
2.19.1 Introduction
An analysis of faults on overhead line network has shown that:
• 80-90% of faults are transient in nature,
• the remaining 10-20% of faults are either non-permanent (arcing faults) or permanent.
A transient fault is a self-clearing ‘non-damage’ fault. This type of fault can be isolated and cleared by the immediate tripping of one or more circuit breakers, and does not reappear when the line is re-energized. The most common causes of transient faults are lightning, insulator flashover, clashing conductors and debris blown by the wind.
The initial trip might not clear a non-permanent or permanent fault, and the use of the reclosing sequence could be necessary in order to clear it. A small tree branch falling on the line could cause a non-permanent fault. Permanent faults could be caused by broken conductors, transformer faults, cable faults or machine faults, which must be located and repaired before the supply can be restored.
Most of the time, if the faulty line is immediately opened, and the fault arc is allowed sufficient time to de-ionize, reclosing the circuit breakers will result in the line being successfully re-energized. Auto-reclosing schemes are used to automatically reclose a switching device once a time-delay started after the CB has opened has elapsed.
On HV/MV distribution networks, the Auto-reclose function is used mainly for radial feeders where system stability problems do not generally arise. Using the auto-recloser minimizes outage time and reduces operating costs.
Automatic reclosing allows a substation to operate unattended: the number of visits to manually reclose a circuit breaker is substantially reduced. This feature constitutes therefore an important advantage for substations supervised remotely.
On circuits using time-graded protection, the auto-recloser allows the use of instantaneous (fast) protection (Fast O/C Trip function in SETTING GROUP x/PROTECTION Gx/[79] AUTORECLOSE Gx menu) to issue a high speed first trip. With fast tripping, the duration of the power arc resulting from an overhead line fault is reduced to a minimum, thus lessening the chance of damage and of the transient fault developing into a permanent fault. To avoid maloperation because of transients, it is possible to assign a short time-delay to the fast trip: Fast O/C Trip Delay setting (SETTING GROUP x/PROTECTION Gx/[79] AUTORECLOSE Gx menu column) above the typical transient time value. The fast trip can be associated with phase-to-phase faults (Fast O/C Trip) and/or earth faults (Fast E/Gnd Trip), separately for every shot in the auto-reclose sequence. If in Fast O/C Trip configuration the setting for chosen trip shot is ‘ 0 ‘, the trip is executed after the time-delay of the protection element. If it is set to ‘ 1 ‘, the time-delay set in the Fast O/C Trip Delay menu cell is applied. In some regions the typical setting of the fast trip for a 2-shot AR is set:
— Fast O/C Trip (trip shots): 00011 (The first and second trips with Fast O/C Trip Delay to reduce to minimum the resulting power arc; The third – final – trip after the time-delay of the protection element to ensure the grading in the power system – trip selectivity)
— Fast E/GND Trip (trip shots): 00000 (alls trips re executed after the time-delays of the protection elements).
Fast O/C Trip – refers to all O/C stages in the PHASE O/C menu column: I>, I>>, I>>>.
Fast E/GND Trip – refers to all E/GND stages in the PHASE E/GND menu column: IN_1, IN_2, IN_3.
Fast O/C (E/GND) Trip Delay is associated with a DMT characteristic even if the protection element is set to an IDMT characteristic. For the fast trip the reset time-delay of the protection element is not applied.
Using a short time-delay prevents the blowing of fuses and reduces circuit breaker maintenance by eliminating pre-arc heating when clearing transient faults.
The figure below shows an example of 4 auto-reclose cycles (maximum numbers of allowed cycles) until the final trip (tD1, tD2, tD3, tD4 = dead times 1, 2, 3 and 4, tR = Reclaim time).

Figure 20: Typical Auto-Reclose Sequence
When short time-delay protection is used with auto-reclosing, the scheme can be arranged to block the instantaneous element after the first trip. Therefore, if the fault persists after re-closing, time-graded protection will issue discriminative tripping with fuses or other protection devices, resulting in the isolation of the faulted section. However, for certain applications, where the majority of the faults are likely to be transient, it is not uncommon to allow more than one instantaneous trip before instantaneous protection stops being applied or the time-delay for fast trip is set.
Some schemes allow a number of re-closings and time-graded trips after the first instantaneous trip, which may result in the burning out and clearance of non-permanent faults. Such an approach may also be used to allow fuses to operate in teed feeders where the fault current is low.
Any decision to apply the Auto-reclose function would be influenced by all known data about the frequency of transient faults (for instance feeders which consist partly of overhead lines and partly of underground cables). When a significant proportion of the faults are permanent, the advantages of auto-reclosing are small, particularly since re-closing on to a faulty cable is likely to compound the damage.
The auto-reclose function has four inputs that can be assigned to the auto-reclosing logic. These inputs can be mapped to opto-isolated inputs in the SETTING GROUP x/PROTECTION Gx/INPUT CONFIGURATION menu. External contacts can then be wired to these inputs and influence the auto-recloser scheme. These four logic inputs are:
— one external CB Faulty signaling,
— two external starting commands,
— one external blocking command.

2.19.1.1 External CB Fail signaling
Most of circuit breakers provide one trip-close-trip cycle. A time-delay is necessary for the CT to return to its nominal state (for example, the spring that allows the circuit breaker to close should be fully charged). The state of the CB can be checked using an input assigned to the CB FLT Ext.Sign. function. If, on completion of the tCB FLT ext time (GLOBAL SETTINGS/CIRCUIT BREAKER submenu), the CB FLT ext (Alarm) indicates a failed state of the CB, a lockout occurs and the CB remains open.
2.19.1.2 External Starting Commands
Two independent and programmable inputs (AUX1 and AUX2) can be used to initiate the auto-reclose function from an external device (such as an existing overcurrent relay). These logic inputs may be used both independently and in parallel with the overcurrent elements.
Notes: 1. The input must be assigned to an AUXx function (SETTING GROUPx/INPUT CONFIGURATION Gx),
2. AUXx must be set to Trip (SETTING GROUP x/PROTECTION Gx/AUX TIMERS Gx/AUXx?) and time-delay tAUXx must be configured (instantaneous: tAUXx set to 0 s),
3. The tAUXx Close Shot cell must be set for every cycle (Close shot).
2.19.1.3 Internal and External Blocking Commands
The auto-recloser can be blocked by an internal or an external control. It can be used when a protection is needed without requiring the use of the auto-recloser function.
The external block is the Block [79] input.
The internal block can be a final trip, a number of [79] rolling demand valid or an [79] conflict.
A typical example is on a transformer feeder, where the Auto-reclose may be initiated from the feeder protection but need to be blocked from the transformer protection side.

The “Auto-reclose in progress” signal is present during the complete reclosing cycles from protection initiation to the end of the reclaim time or lockout.
2.19.2.2 Final trip
The «Final trip» signal indicates that a complete auto-reclose cycle has been performed and that the fault has been cleared.
The «Final trip» signal can be reset after a manual closing of the CB after the settable Inhibit Time tI on Close (GLOBAL SETTINGS/ [79] ADVANCED SETTING) time-delay or reset via a Reset Command
2.19.3 Auto-reclose Logic Description
The auto-reclose function makes it possible to automatically control the CB’s reclosing cycles (two, three or four shot cycle, settable using the Close Shot ? parameter – separate for each O/C and E/GND protection element (SETTING GROUP x/PROTECTION Gx/[79] AUTO-RECLOSE Gx menu).
Dead times for all the shots (reclose attempts) can be independently adjusted.
The number of shots is directly related to the type of faults likely to occur on the system and the voltage level of the system (for instance medium voltage networks).
The Dead Time (tD1, tD2, tD3 and tD4) and the minimum drop-off time start when the CB has tripped (when the 52a input has dropped off – Start Dead t on 1: CB trips or the protection element has reset – Start Dead t on 0: Protect.Reset configuration option). The Dead Time is set to initiate the auto-recloser when the circuit breaker is opened.
At the end of the relevant dead time the close command (Close CB Order) is executed and the CB supervision timer is started. The length of this timer is equal to: tClose Pulse (GLOBAL SETTINGS/CIRCUIT BREAKER) + 150 ms. If the CB is not closed after this time-delay, the auto-recloser is locked out and Alarm is issued (Alarm CB Time Monitor).
The reclaim time (Reclaim Time tR) starts when the CB has closed. If the circuit breaker does not trip again, the Auto-reclose function resets at the end of the reclaim time.

If a protection element operates during the reclaim time, the relay either advances to the next shot programmed in the auto-reclose cycle, or it locks out (see Inhib.Trip function description).
The total number of reclosures is displayed in the RECORDS/ COUNTERS/ AUTORECLOSE COUNTER menu cell.
2.19.4 Auto-reclose Inhibit Trip
The trip inhibit is used for following cases: — e/f protection in neutral-insulated or compensated systems. The A/R can clear a non-
permanent fault in the first cycles. If it will be permanent fault, there will be no the final trip up to reset of the protection trip.
— application where for example the setting for the I> stage covers more than the protected zone, so that the [79] can clear faults downstream too, but the final trip will be executed by the downstream relay or a fuse, therefore in the upstream relay, tI> should be inhibited – waiting for tI>> trip of the downstream relay). Note: for this case Fast Trip O/C function can be used too (see below).
It is recommended to set another protection stage with setting for Alarm only, to inform that this fault was not cleared by autorecloser so it’s still present (tripping from this protection element is inhibited). For above case when the auto-reclose is successful, the reset of inhibition is applied after reset of protection stage (current below the stage value). For another case when during inhibition of protection element, another protection element (set to run [79]) makes a trip after going to the next cycle (the next A/R close command is executed) the inhibition is reset and the further action depends on the configuration: — if in the next cycle this protection element is still set with inhibition, the protection
element is still inhibited — if in the next cycle this protection element is not set with inhibition, but the fault is still not
cleared, this protection element will trip CB (If another protection element moves auto-reclose to the next cycle, the inhibition is removed automatically and [79]logic checks configuration for the next [79] shot).
2.19.5 Auto-reclose Inhibit after Manual Closing
The Inhibit Time tI on Close timer (GLOBAL SETTINGS/ [79] ADVANCED SETTING) can be used to block the auto-reclose cycle being initiated after the CB has been manually closed onto a fault. The Auto-reclose is blocked for the duration of Inhibit Time tI on Close after a manual CB Closure (The blocking indication: [79] blocked, the reason of blocking: [79] Tempor.Block).
2.19.6 Recloser lockout
If a protection element operates during the reclaim time, following the final reclose attempt, the relay will lockout and the auto-reclose function will be disabled until the lockout condition is reset.
The lockout condition can be reset by a manual closure after the Inhibit Time tI on Close timer elapses.
The auto-recloser can also be locked out using a CB FLT Ext.Sign. input. This information can be issued from the «not charged» or «Low gas pressure» indications of CB springs.
Note that the auto-recloser can also be locked out by:
• The fact that the CB does not open after the tBF delay (CB Fail) elapses,
• An operating time longer than the set thresholds,
• Local or remote manual Close or Open command when the auto-reclose is in progress,
• The Rolling Demand function detects too many auto-reclose shots.
In the lockout condition the ALARM with the cause: ALARM [79] Lockout is displayed up to reset of the lockout condition.

2.19.10 Signaling Reset after Close via 79
In the GLOBAL SETTINGS/ [79] ADVANCED SETTING menu it is possible to set the signaling reset after a close command executed by the auto-recloser. If Signaling Reset is set to 1: Close via 79, after the auto-recloser’s close shot (confirmed by the 52a CB status), signaling (LEDs, display) of the last trip before the close shot is reset:
— Latched LEDs
— Trip information on the P111Enh’s front panel
— Electromagnetic Flag Indicators on the Front Panel
— Latched outputs
This function signals the final trip only and clears signaling if the CB remains closed (Auto-reclose is successful). This function is recommended if the P111Enh is integrated into a SCADA system or if the substation is rarely supervised by maintenance personnel. In this case it is not necessary to clear signaling if the fault has disappeared and the line is healthy.
Note: Reset of signaling and of latched outputs can be done using the General resetting function.
This configuration can be set in the GLOBAL SETTINGS/LOC submenu:
— LEDs Reset:
o 0: Manual only (via Inputs, HMI key, Remote Reset command)
o 1: Start protect. (Start of the protection element set to Trip)
— Ltchd Outp. Reset:
o 0: Manual only (via Inputs, HMI key, Remote Reset command)
o 1: Start protect. (Start of the protection element set to Trip)
The Manual only option prevents a close command from being issued without readout of the cause of trip by maintenance personnel. It reduces the risk to switch on to fault.
The Start protect option allows signaling of the latest trip only.

2.19.11 Setting Guidelines
2.19.11.1 Number Of Shots
There is no perfect rule to define the number of shots for a particular application.
In medium voltage systems it is common to use two or three auto-reclose shots, and, for specific applications, four shots. Using four shots, the final dead time can be set to a time long enough to allow thunderstorms to end before the final reclosure. This scheme prevents unnecessary lockout caused by consecutive transient faults.
Typically, the first trip, and sometimes the second, are caused by the instantaneous protection element. Since 80% of faults are transient, further trips will be time-delayed, and all will have increasing dead times so as to clear non-permanent faults.
In order to determine the required number of shots, the first factor is the ability for the circuit breaker to perform several trip-close operations in a short time and the effect of these operations on the maintenance period.
If a moderate percentage of non-permanent faults are present in a system, two or more shots are justified. If fused ‘tees’ are used and the fault level is low, the timer of the fuses may not discriminate with the main IDMT relay: several shots are useful. This would not warm up the fuse to such an extent that it would eventually blow before the main protection element operated.
2.19.11.2 Dead Time Setting
Load, circuit breaker, fault de-ionizing time and protection reset are taken into consideration when setting the dead time.
2.19.11.3 Minimum Drop-Off Time Setting
If an electromagnetic relay is used (working on the principle of disc in the electromagnetic field due to eddy current generated in the disc), an additional dead time (Min Drop-off Time), depending of the trip cause, is settable.
This function includes the choice to select an IDMT curve on the relay’s reset time, setting the drop-off time on phase and neutral auto-reclose cycles.
This drop-off time blocks the next cycle if the current one has not elapsed.
A new cycle can start if both the dead time and tReset have elapsed.

2.19.11.3.1 Load
It is very difficult to optimize the dead time due to the great diversity of loads on a system. However, it is possible to study each type of load separately and thereby be able to define a typical dead time.
The most common types of loads are synchronous or induction motors and lighting circuits.
Synchronous motors tolerate only extremely short interruptions of supply without loss of synchronism. In practice, the dead time should be sufficient to allow the motor no-volt device to operate. Typically, a minimum dead time of 0.2-0.3 second is recommended.
Induction motors, on the other hand, can withstand supply interruptions, up to a maximum of 0.5 second and re-accelerate successfully. In general dead times of 3-10 seconds are normally satisfactory, but there may be special cases for which additional time is required to allow the reset of manual controls and safety devices.
Loss of supply of lighting circuits, such as street lighting, can lead to important safety problems (car circulation). Regarding domestic customers, the main consideration is linked to the inconvenience caused.
The number of minutes lost per year to customers will be reduced on feeders using the auto-recloser and will also be affected by the dead time settings used.
2.19.11.3.2 Circuit Breaker
For high speed reclosing, the minimum dead time of the power system depends on the minimum time-delay imposed by the circuit breaker during a trip and reclose operation.
Since a circuit breaker is a mechanical device, it has an inherent contact separation time. This operating time for a modern circuit breaker is usually within the 50-100 ms range, but could be longer with older designs.
After a trip, the mechanism needs some time to reset before applying a close pulse. This reset time varies depending on the circuit breaker, but lasts typically 0.1 second.
Once the circuit breaker has reset, the breaker can start to close. The period of time between the energization of the closing mechanism and the making of the contacts is called closing time. Because of the time constant of a solenoid closing mechanism and the inertia of the plunger, a solenoid closing mechanism may take 0.3 s. A spring-operated breaker, on the other hand, can close in less than 0.2 second.
Where high speed reclosing is required, for the majority of medium voltage applications, the circuit breaker mechanism dictates itself the minimum dead time. However, the fault de-ionizing time may also have to be considered.
High speed reclosing may be required to maintain stability on a network that has two or more power sources. For high speed reclosing, the system disturbance time should be minimized using fast protection, <50 ms, such as distance or feeder differential protection and fast circuit breakers < 100 ms. Fast fault clearance can reduce the time for the fault arc to de-ionize.
To ensure stability between two sources, a dead time of less than 300 ms is typically required. Considering only the CB, this minimum time corresponds to the reset time of the mechanism plus the CB closing time. Thus, a solenoid mechanism is not adapted for high speed reclosing due to the fact that the closing time is generally too long.
2.19.11.3.3 Fault De-ionizing Time
For high speed reclosing, the time to de-ionize faults may be the most important factor when considering the dead time. This is the time required for the ionized air to disperse around the fault location so that the insulation level of the air is restored. This time may be around the following value:
De-ionizing time = (10.5 + ((system voltage in kV)/34.5)) / frequency
For 66 kV = 0.25 s (50 Hz)
Application Notes
P111Enh_EN_AP v1.3 MiCOM P111Enh (AP) 6-51
AP
For 132 kV = 0.29 s (50 Hz)
2.19.11.3.4 Protection Reset
It is essential that the protection device fully resets during the dead time, so that correct time discrimination is maintained after reclosing on to a fault. For high speed reclosing, instantaneous protection reset is required.
Typical 11/33 kV dead time settings in the UK are as follow:
1st dead time = 5 — 10 seconds
2nd dead time = 30 seconds
3rd dead time = 60 — 100 seconds
4th dead time (uncommon in the UK, however used in South Africa) = 60 — 100 seconds
2.19.11.4 Reclaim Time Setting
The following factors influence the choice of the reclaim time:
• Supply continuity — Large reclaim times can result in unnecessary lockout for transient faults.
• Fault incidence/Past experience — Small reclaim times may be required where there is a high incidence of lightning strikes to prevent unnecessary lockout for transient faults.
• Charging time of the spring or resetting of electromagnetical induction disk relay — For high speed reclosing, the reclaim time may be set longer than the spring charging time to ensure that there is sufficient energy in the circuit breaker to perform a trip-close-trip cycle. For delayed reclosing, this setting is of no need as the dead time can be extended by an extra CB healthy check window time if there is insufficient energy in the CB. If there is insufficient energy after the check window time the relay will lockout.
• Switchgear Maintenance — Excessive operation resulting from short reclaim times can mean shorter maintenance periods. A minimum reclaim time of 5 s may be needed to give sufficient time to the CB to recover after a trip and close before it can perform another trip-close-trip cycle.
The reclaim time must be long enough to allow any time-delayed protection leading the auto-recloser to operate. Failure to do so can cause the auto-recloser to reset too soon and the reactivation of the instantaneous protection.
If that were the case, a permanent fault would look like a sequence of transient faults caused by repeated auto-recloses. Applying protection against excessive fault frequency lockout is an additional precaution that can solve this problem.
It is possible to obtain short reclaim times to reduce the number of CB lockouts by blocking the reclaim time from the protection start signals. If short reclaim times are to be used, then the switchgear rating may dictate the minimum reclaim time.
Sensitive earth fault protection is used to detect high resistance earth faults. The time-delay of such protections is usually a long time-delay, typically about 10-15 s. If auto-reclosing is caused by SEF protection, this timer must be taken into account when deciding the value of the reclaim time, if the reclaim time is not blocked by an SEF protection start signal. Sensitive earth faults, caused by a broken overhead conductor in contact with dry ground or a wood fence are rarely transient faults and may be dangerous to people.
It is therefore common practice to block the auto-recloser using the sensitive earth fault protection element and to lockout the circuit breaker.
Where motor-wound spring closed circuit breakers are used, the reclaim time must be at least as long as the spring winding time for high speed reclosing to ensure that the breaker can perform a trip-close-trip cycle.
A typical 11/33 kV reclaim time is 3-10 seconds, this prevents unnecessary lockout during thunderstorms. However, times up to 60-180 seconds may be used.

2.20 Circuit Breaker State Monitoring (Model A and E)
An operator at a remote location requires a reliable indication of the state of the switchgear. Without an indication that each circuit breaker is either open or closed, the operator has insufficient information to decide on switching operations. The MiCOM P111Enh relays incorporate a circuit breaker state monitoring feature, giving an indication of the position of the circuit breaker.
This indication is available either on the relay’s front panel or via the communication network.
The positions of the CB contacts can be selected under the SETTING GROUP x/INPUTS CONFIGURATION Gx and SETTING GROUP x/LEDs CONFIGURATION Gx menus using AUX5 (in parallel with CB Status 52A) and AUX6 (in parallel with CB Status 52B).
AUX5 (CB closed) and AUX6 (CB opened) must be assigned to LEDs in SETTING GROUP x/LEDs CONFIGURATION Gx menu.
Furthermore, the MiCOM P111Enh relays can inform the operator that the CB has not opened following a remote trip command (refer to section “CB FAIL protection”).
2.21 Circuit Breaker Condition Monitoring
Periodic maintenance of circuit breakers is generally based on a fixed time interval, or a fixed number of fault current interruptions.
The relays record the following controls and statistics related to each circuit breaker trip operation:
• time-delay setting,
• monitoring time for CB open and close operations,
• CB open count,
• summation of the current interrupted by the CB,
• exponent for the summation,
• tripping and closing pulse time
2.22 Circuit Breaker Condition Monitoring Features
For each circuit breaker trip operation the relay records statistics as shown in the following table taken from the relay menu. The RECORDS/COUNTERS/CB Monitoring menu cells shown are counter values only.
The circuit breaker condition monitoring counter increases when it receives:
— a protection trip command (Prot.Trip pulse),
— an HMI (or MiCOM S1) opening command (Trip CB Order ),
— a rear com opening command (Trip CB Order ),
— a digital input opening command (Trip CB Order ).
In cases where the breaker is tripped by an external protection device it is also possible to update the CB condition monitoring. This is achieved by assigning one of the logic inputs or via the communication to accept a trigger from an external device.

2.23 Setting guidelines
2.23.1 Setting the Σ In Threshold
Where overhead lines are prone to frequent faults and are protected by oil circuit breakers (OCB’s), oil changes account for a large proportion of the life cycle cost of the switchgear. Generally, oil changes are performed at a fixed interval of circuit breaker fault operations. However, this may result in premature maintenance where fault currents tend to be low, and hence oil degradation is slower than expected.
The Σ In counter monitors the cumulative severity of the duty placed on the interrupter allowing a more accurate assessment of the circuit breaker condition.
For OCB’s, the dielectric withstand of the oil generally decreases as a function of Σ I2t. This is where ‘I’ is the fault current broken, and ‘t’ is the arcing time within the interrupter tank (not the interrupting time). As the arcing time cannot be determined accurately, the relay would normally be set to monitor the sum of the broken current squared, by setting n = 2.
For other types of circuit breaker, especially those operating on higher voltage systems, practical evidence suggests that the value of n = 2 may be inappropriate. In such applications n’ may be set to 1.
An alarm in this instance may be indicative of the need for gas/vacuum interrupter HV pressure testing, for example.
It is imperative that any maintenance program must be fully compliant with the switchgear manufacturer’s instructions.
2.23.2 Setting the Number of Operations Threshold
Every operation of a circuit breaker results in some degree of wear for its components. Thus, routine maintenance, such as oiling of mechanisms, may be based upon the number of operations. Suitable setting of the maintenance threshold will allow an alarm to be raised, indicating when preventative maintenance is due.
Should maintenance not be carried out, the relay can be set to lockout the auto-reclose function upon reaching a number of operations. This prevents further reclosure when the circuit breaker has not been maintained to the standard required by the switchgear manufacturer’s maintenance instructions.
Certain circuit breakers, such as oil circuit breakers (OCB’s) can only perform a certain number of fault interruptions before requiring maintenance attention. This is because each fault interruption causes carbonizing of the oil, degrading its dielectric properties.
2.23.3 Setting the Operating Time Threshold
Slow CB operation is also indicative of the need for mechanism maintenance. Therefore, an alarm is provided and is settable in the range of 100 ms to 5 s. This time is set in relation to the specified interrupting time of the circuit breaker.

2.24 Circuit Breaker Failure Protection: CB Fail
When a fault is detected, one or more main protection elements will issue a trip command to the associated circuit breaker(s). To isolate the fault, and prevent (further) damage to the power system it is essential that the circuit breaker operates correctly.
A fault that is not cleared quickly enough threatens the stability of the system. It is therefore common practice to install circuit breaker failure protection devices/elements that check that the circuit breaker has opened within a reasonable period of time. If the fault current has not been eliminated after the set time-delay, breaker failure protection (CB Fail) will send a signal.
The CB Fail protection element can be used to back-trip upstream circuit breakers to ensure that the fault is correctly isolated. The CB Fail protection element can also clear all blocking commands associated with logic selectivity.
Figure 21: CB Fail Principle
The tBF timer is initiated when a trip command is issued by a protection element. Note that the trip command can be issued either by a protection element, or by a logic input (ABE) assigned to an AUX counter. Then the relay monitors the current signal of each phase and compares each phase current signal with the bandzone made by the undercurrent I< threshold. This value can be set under the SETTING GROUP x/PROTECTION Gx / [50BF] CB FAIL Gx menu.
The selection in the relay menu is grouped as follows:

• Retrip: a retrip signal is issued concurrently with the tCBF output (Protect.Trip and Prot.Trip pulse output). The TRIP LED and FLAG are activated,
• Alarm: typical setting. In case of CB Failure, an alarm is issued concurrently with the tCBF output. The Alarm LED is lit,
must be set in order to enable CB Fail protection.
2.24.1 Typical settings
2.24.1.1 Breaker Fail Timer Settings
The typical timer settings to use are as follows:
CB fail reset mechanism tBF time-delay Typical delay for 2 cycle circuit breaker
Initiating element reset CB interrupting time + element reset time (max.) + error in tBF timer + safety margin
50 + 50 + 10 + 50 = 160 ms
CB open
CB auxiliary contacts opening/ closing time (max.) + error in tBF timer + safety margin
50 + 10 + 50 = 110 ms
Undercurrent elements CB interrupting time + undercurrent element (max.) + safety margin operating time
50 + 25 + 50 = 125 ms
Note that all the CB Fail resetting methods involve the operation of the undercurrent element. Where element reset or CB open resetting is used the undercurrent time setting should still be used if this proves to be the worst case.
The examples above consider direct tripping of a circuit breaker. Note that where auxiliary tripping relays are used, an additional 10-15ms must be added to allow for trip relay operation.
2.24.1.2 Breaker Fail Undercurrent Settings
The phase undercurrent threshold (I<) must be set below the load current, to ensure that I< operation indicates that the circuit breaker pole is open. A typical setting for overhead lines or cable circuits is 20% In, with 5% In common for generator circuit breaker CBF.
The standard earth fault undercurrent element must be set to less than the trip setting, typically as follows:
IN< = (IN> trip) / 2

2.25 Trip Circuit Supervision (Model A and E)
The trip circuit extends beyond the relay enclosure and passes through more components, such as fuse, wires, relay contacts, auxiliary switch contact and so on.
These complications, coupled with the importance of the circuit, have directed attention to its supervision.
The simplest arrangement for trip circuit supervision contains a healthy trip lamp in series with a resistance placed in parallel with a trip output relay contacts of the protection device.
2.25.1 Trip Circuit Supervision Mechanism
The Trip Circuit Supervision function included in the MiCOM P111Enh relays is described below:
A logic input is assigned to the GLOBAL SETTINGS/CIRCUIT BREAKER/TC Supervision? function. This logic input is labeled Trip Circ Supervis. in the SETTING GROUP x/INPUTS CONFIGURATION Gx menu. This logic input is then wired to the trip circuit according to one of the typical application scheme examples shown below.
When the TC Supervision function is set to «Yes» under the TC Supervision? sub-menu, the relay checks continuously the trip circuit continuity whether the CB status is CB opened or CB closed.
When the TC Supervision function is set to Yes-52A under the CIRCUIT BREAKER sub-menu, the relay checks continuously on trip circuit continuity in case when the CB’s status is closed only.
The TC Supervision function is enabled when the Prot.Trip pulse and Trip CB order outputs are not energized. The TC Supervision function is not enabled when the Prot.Trip pulse and Trip CB order output are energized.
An Alarm: TC Supervision (trip circuit failure) signal is generated if the logic input detects no voltage signal for a time longer than the settable timer tSUP. See Chapter P111Enh/EN OP (Operation) and Chapter P111Enh/EN TD (Technical Data) for the settings.
As this function is disabled when the Prot.Trip pulse and Trip CB order outputs are energized, it is suitable for use with the output latching logic disabled.
The tSUP timer can be set according to the following table:

2.26 Real time clock synchronization via opto-inputs (Model B and E)
In modern protection schemes it is often desirable to synchronize the relay’s real time clock so that events from various relays can be placed in chronological order. This can be done using the communication interface connected to the substation control system or via a binary input. Any of the available binary inputs on the P111Enh relay can be selected for synchronization. Pulsing this input will result in the real time clock snapping to the nearest minute. The recommended pulse duration is 20 ms to be repeated no more than once per minute. An example of the time synchronization function is shown.
Time of “Sync. Pulse” Corrected Time
19:47:00.000 to 19:47:29.999 19:47:00.000
19:47:30.000 to 19:47:59.999 19:48:00.000
Note: The above assumes a time format of hh:mm:ss
The input is configured in the SETTING GROUPx/INPUT CONFIGURATION Gx menu. The input must be assigned to Time Synchr.

2.27 Event Records
The relay records and time-tags up to 200 events and stores them in a non-volatile (Fram) memory. This allows the system operator to analyze the sequence of events that has occurred within the relay after a particular power system condition, or switching sequence, etc. When the available space is exhausted, the new fault automatically overwrites the oldest fault.
The real time clock within the relay time-tags each event, with a resolution of 1 ms.
The user can view the event records either locally via the USB port, or remotely, via the rear EIA(RS)485 port.
2.28 Fault Records
Each time any of the set protection elements trips (Protect.Trip output), a fault record is created and stored in memory. The fault record tags up to 20 faults and stores them in a non-volatile (Fram) memory. This allows the operator to identify and analyze system failures. When the available memory space is exhausted, the new fault automatically overwrites the oldest fault.
The user can view the latest fault record in the RECORD/FAULT RECORDS menu, where he or she can choose to display up to 20 stored records. These records are the fault flags, the fault measurements, etc. Also note that the time stamp displayed in the fault record itself will be more accurate than the corresponding time stamp given in the event record. This is due to the fact that events are logged some time after the actual fault is recorded.
The user can view event records either via the front panel interface, via the USB port, or remotely, via the rear EIA (RS) 485 port.
2.29 Instantaneous Recorder (Model E)
Each time any of set thresholds are crossed, an instantaneous record is created and displayed in the RECORDS/INSTANTANEOUS RECORD menu. The last five starting records are available, with the duration of the signal.
The following information is displayed in the RECORDS/INSTANTANEOUS RECORD menu: number of starts, time, date, origin (crossing of a current threshold or start of a protection element’s time-delay), current values.
Instantaneous Recorder is memorized if P111Enh is powered from auxiliary voltage (Vx).
2.30 Alarm Recorder
Each time any of the programmed protection element makes ALARM signal (Alarm output), an Alarm record is created and stored in memory. The fault record tags up to 5 faults and stores them in a non-volatile (Fram) memory. This allows the system operator to identify and analyze network failures. When the available memory space is exhausted, the new fault automatically overwrites the oldest Alarm.
The user can view actual Alarm record under the RECORD/ALARM RECORDS menu, where he can select to display up to 5 stored records. These records are Alarm flags, Alarm measurements, etc. Also note that the time stamp displayed in the Alarm record itself will be more accurate than the corresponding time stamp given in the event record.

2.31 Disturbance Recorder (Model A and E)
The integral disturbance recorder has a memory space specifically dedicated to the storage of disturbance records. Up to 3 seconds of disturbance recording can be stored. When the available memory space is exhausted, the new record automatically overwrites the oldest record.
The recorder stores actual samples that are taken at a rate of 16 samples per cycle.
Each disturbance record consists of analogue and digital channels. (Note that the relevant CT ratios for the analogue channels are also extracted to enable scaling to primary quantities).
The disturbance recorder is set in the GLOBAL SETTINGS/DISTURBANCE RECORDER menu.
The total disturbance recording time is 3 s but not more than 5 records are available.
Total number of records available in disturbance recorder is:
o One — for set Max Record Time from in range: 1.51s — 3s
o Two – for set Max Record Time from in range: 1.01s – 1.5s
o Three – for set Max Record Time from in range: 0.76s — 1s
o Four – for set Max Record Time from in range: 0.61s – 0.75s
o Five — for set Max Record Time from in range: 0.10s – 0.6s
Triggering of disturbance recording depends on the Disturb.Rec.Trig. configuration:
— 0: on Inst. – Start of a protection element set to Trip,
— 1: on Trip – Trip by a protection element followed by the Protect.Trip output.
If the 0: on Inst. option is selected the record consists of: Pre-fault time + duration of the «any Start» signal presence + Post-fault time.
If the 1: on Trip option is selected the record consists of: Pre-fault time + duration of the Trip signal presence (Protect.Trip function active) + Post-fault time.
The pre-fault time can be set in the cell: GLOBAL SETTINGS/DISTURBANCE RECORDER/Pre-Time. If the pre-fault time is set to 100 ms, recording starts 100 ms before the disturbance.
The post trip time can be set in the cell: GLOBAL SETTINGS/DISTURBANCE RECORDER/Post Trip Time. If the post-fault time is set to 100 ms, recording stops 100 ms after the disturbance.

3. CT REQUIREMENTS For the conventional case of a resistive load, the voltage at the secondary winding of the transformer is proportional to the primary current, therefore the error remains constant.
In the case of a MiCOM P111Enh self-powered protection relay, this no longer applies, since the voltage at the input of the protection circuit is in a non-proportional ratio to the input current.
The best solution to check whether the MiCOM P111Enh relay is adapted to a given CT is to have available the magnetization curve and the internal resistance of the CT in question.
To guarantee good accuracy at low current levels, the magnetizing current of the CT must be low. In other words, the input voltage of the relay must be sufficiently low compared with the knee-point voltage Vk of the CT.
The following sections show the ac burden of the P111Enh MiCOM relay and, taking into account the magnetizing curve of a CT, it is then possible to determine the accuracy of the system as a whole for the entire current range: P111Enh + associated CT.
3.1 Recapitulation of the Current Transformer’s Characteristics
3.1.1 Characterization of a Current Transformer
The characteristics of a protection relay CT are based on:
• Its rated output burden expressed in VA, its relevant accuracy class (5P or 10P) and the accuracy limit current (5 In, 10 In, 15 In, 20 In). The accuracy limit factor (K) is the ratio between the precision limit current and the nominal current rating.
• Naturally, the transformation ratio of the CT is to be added to this. This ratio is the ratio of the primary current to the secondary current I1/I2. The secondary current rating is generally 1 A or 5 A.
• Other characteristics such as the insulating voltage or the thermal behavior are also taken into account.
Standard BS 3938 proposes a specification identical to that of IEC 185 for class P transformers. The CT is characterized in accordance with a second class known as X class (Cx) which, in addition to the calculated ratio, requires a knee-point voltage Vk and an internal resistance Rct.
The following quantities are associated with the magnetization curve of a CT:
• The knee-point voltage Vk, which is determined by the point on the curve V=f (Im) beyond which an increase of 10% in the voltage V results in a 50% increase of the magnetizing current.
• The voltage related to the accuracy limit of the CT.
— For a 5PK CT (accuracy class 5P, accuracy limit factor K):
At the saturation voltage Vs1 we will have a 5% accuracy on the current K * In.
— For a 10PK TC (accuracy class 10P, accuracy limit factor K):
At the saturation voltage Vs2 we will have a 10% accuracy on the current K * In

With the materials generally used to manufacture current transformers, we have:

The equivalent diagram of a CT is indicated below:
• CT ratio: n2/n1
• Lm: magnetization self-induction coil of the CT
• Im: magnetizing current
• I1: primary current
• I2: secondary current = I1 * n2 /n1
• Is: secondary current passing through the load resistance Rp.: mS III −= 2
• Rct: secondary winding resistance of the CT (ohms)

Figure 29: Equivalent diagram of a current transformer
The magnetizing current Im of the transformer depends on the voltage generated at the secondary windings of the transformer.
It is this current that introduces an error signal into the measurement. If the CT were perfect, the magnetizing current would be null.
3.1.3 How to calculate the rated burden, in VA, of a CT based on its characteristic quantities (Vk, Rct)
The saturation voltage is derived using the following formula: Vs = (Rct + Rp ) Is
The nominal load impedance of the CT is Rp = Pn /In2
We have Vs = (Rct + Pn /In2 ) Is
Hence: Pn = (Vs/Is — Rct ) In2
• For a transformer with in a 5P accuracy class: Vs1/Vk = 1.6/1.4
Thus: Vs1 = 1.6/1.4 * Vk, at Is1 equals K * In
Hence: Pn = [(1.6/1.4 * Vk )/K * In — Rct ] * In2
• For a transformer with a 10P accuracy class: Vs2/Vk = 1.9/1.4
thus Vs2 = 1.9/1.4 * Vk, at Is2 equals K * In
Hence: Pn = [(1.9/1.4 * Vk )/K * In — Rct ] * In2
3.1.4 Definition equivalence for common CTs
Since the only constants of a CT are its magnetizing curve, its Rct resistance and its transformation ratio, it is possible to replace a transformer which Pn1 power in VA is of the 5PK1 type with a transformer which Pn2 power in VA is of the 5PK2 type.
Given that the values of Vs1 and Rct are known:
Vs1 = (Rct +Pn1/In2 )*K1 * In = (Rct + Pn2/In2 )*K2 *In
Pi = Rct * In2 (ohmic lossof CT)
(Pi +Pn1) * K1 = (Pi + Pn2 ) * K2
Hence K2 = [(Rct * In2 + Pn1 )/ (Rct * In2 + Pn2 )] * K1

3.1.5 How to calculate the knee-point voltage Vk of a CT defined in class P
• For a transformer with accuracy class of 5P: Vs1/Vk = 1.6/1.4
Pn = [(1.6/1.4 * Vk )/K* In — Rct ] * In2
Hence Vk = 1.4/1.6 (Pn/In2 + Rct) K * In
• For a transformer with a precision class 10P: Vs2/Vk = 1.9/1.4
Pn = [(1.9/1.4 * Vk )/K* In — Rct ] * In2
Hence Vk = 1.4/1.9 (Pn/In2 + Rct) K * In.

• Type of CT (nominal power, nominal current and current ratio, internal resistance, nominal accuracy limit factor, class and construction),
• Resistance of wiring (length, cross section, specific resistance of material),
• Resistance of P111Enh current inputs (as per table 2 in section 3.2).
Depend on the regional standards and the best practice two ways of calculation is possible:
— The first method gives the minimum CT requirement to be sure that the relay trips
— The second method assures that CTs will be not saturated at all conditions (DC component in fault condition). This method is recommended for full functionality (measurement, recording in full range, etc) of the relay.
Note: Assuming that the CT does not supply any circuits other than the MiCOM P111Enh and the distance between P111Enh and CTs is short, the folowing CTs types are recommended as minimum:
— 5VA 10P20 for 1A secondary rating
— 10VA 10P20 for 5A secondary rating

The second method:
Two critical cases have to be checked for different types of faults:
• the lowest set current threshold value at which the relay has to operate (minimum current).
• the highest possible short-circuit current, which depends on the maximum short-circuit power on the busbar of the substation (maximum current).

4. AUXILIARY SUPPLY FUSE RATING In the Safety section of this manual, the maximum allowable fuse rating of 16 A is quoted. To allow time grading with upstream fuses, a lower fuse link current rating is often preferable. Use of standard ratings of between 6 A and 16 A is recommended. Low voltage fuse links, rated at 250 V minimum and compliant with IEC 60269-2 general application type gG, with high rupturing capacity are acceptable. This gives equivalent characteristics to HRC «red spot» fuses type NIT/TIA often specified historically.
The table below recommends advisory limits on relays connected per fused spur. This applies to the MiCOM P111Enh, as these have inrush current limitation on switch-on, to conserve the fuse-link.

1. MEASUREMENTS AND RECORDING 1.1 Introduction
The P111Enh is equipped with integral fault recording facilities suitable for analysis of complex system disturbances. Fault records can be read out by setting software MiCOM S1 via the USB port accessible on the P111Enh front panel. The USB port offers a communications facility to the P111Enh.
Communications can be established via the USB port even if the P111Enh is not supplied by the auxiliary voltage ( function not available in Model N).
Access to the USB port is protected by means of a plastic cover.
1.2 Event records (not available in Model L w/o RS485)
The relay records and time tags up to 200 events and stores them in non-volatile FRAM memory. This enables the system operator to establish the sequence of events that occurred within the relay following a particular power system condition, switching sequence etc. When the available space is exhausted, the oldest event is automatically overwritten by the most recent.
The real time clock within the relay provides the time tag for each event, to a resolution of 1 ms.
The event records are available for remote viewing, via the communications ports RS485 or USB.
For extraction from a remote source via communications ports, refer to the SCADA Communications section (P111Enh/EN CT), where the procedure is fully explained.
Types of event
An event may be a change of state of a control input or output relay, a trip condition, etc. The following sections show the various items that constitute an event:
Change of state of binary inputs (ABE)
If one or more of the binary inputs has changed state since the last time that the protection algorithm ran, the new status is logged as an event. The information is available if the event is extracted and viewed via a PC.
Change of state of one or more output relay contacts
If one or more of the output relay contacts have changed state since the last time that the protection algorithm ran, then the new status is logged as an event. The information is available if the event is extracted and viewed via PC.
Relay alarm conditions
Any alarm conditions generated by the relays will also be logged as individual events. The following table shows examples of some of the alarm conditions and how they appear in the event list:
Alarm Condition Event Text Event Value
Auxiliary Supply Fail Vx Fail ON/OFF Bit position 0 in 32 bit field
CT Supply Fail CT Supply Fail ON/OFF Bit position 1 in 32 bit field
The above table shows the abbreviated description that is given to the various alarm conditions and also a corresponding value between 0 and 31. This value is appended to each alarm. It is used by the event extraction software, such as MiCOM S1, to identify the alarm. Either ON or OFF is shown after the description to signify whether the particular condition is operational or has reset.

MR
Protection element trips
Any operation of protection elements (a trip condition) will be logged as an event record, consisting of a text string indicating the operated element and an event value. Again, this value is intended for use by the event extraction software, such as MiCOM S1.
1.3 Fault records
Each fault record is generated with time stamp.
The following data is recorded for any relevant elements that operated during a fault, and can be viewed in each of the last 20 fault records:
(i) Event Text (the reason for a trip):
Phase Overcurrent: I> trip I>> trip I>>> trip SOTF trip (ABE) IN_1 trip IN_2 trip IN_3 trip (E) I2> trip (E) Brkn Cond (E) trip CB Fail trip AUX1 trip (ABE) AUX2 trip (ABE) AUX3 trip (ABE) AUX4 trip (ABE) Therm OL (NABE) (ii) Active setting Group
(iii) Fault Time an Fault Date
(iv) Fault Orgin: type of fault (for example: phase A-B, A-B-C, etc)
(v) Event Value:
Per phase record of the current value during the fault: Iϕ and measured IN
Fault records are stored in non-volatile memory (FRAM memory). This type of memory does not require any maintenance (no battery inside the P111Enh). Fault records are stored without any time limitation even if the P111Enh is not supplied from any power source.
1.4 Alarm records
Each alarm record is generated with time stamp.
The following data is recorded for any relevant elements that operated during an alarm, and can be viewed in each of the last 5 alarm records:
(i) Event Text (the reason for a protection alarm):
Phase Overcurrent: tI> Alarm tI>> Alarm tI>>> Alarm tSOTF Alarm (ABE) tIN_1 Alarm tIN_2 Alarm tIN_3 Alarm (E) tI2> Alarm (E) tBrkn Cond Alarm (E) tCB Fail Alarm tAUX1 Alarm (ABE)

Alarm records are stored in non-volatile memory (FRAM memory). This type of memory does not require any maintenance (no battery inside the P111Enh). Alarm records are stored without any time limitation even if the P111Enh is not supplied from any power source.
1.5 Instantaneous records (Model E)
Each instantaneous record is generated with time stamp.
The following data is recorded for any relevant current elements with the crossed threshold, and can be viewed in each of the last 5 instantaneous records:
(i) Event Text (the reason for a current protection start):
Phase Overcurrent: I> I>> I>>> SOTF IN_1 IN_2 IN_3 (ii) Active setting Group
(iii) Alarm Time an Alarm Date
(iv) Alarm Orgin: type of alarm (for example: phase A-B, A-B-C, etc)
(v) Event Value:

Instantaneous records are recorded in case of powering from an auxiliary voltage (not recorded if P111Enh is powered from CTs only) and stored in non-volatile memory (FRAM memory). This type of memory does not require any maintenance (no battery inside the P111Enh). Instantaneous records are stored without any time limitation even if the P111Enh is not supplied from any power source.

1.9 Disturbance Recorder (Model A and E)
The integral disturbance recorder has an area of memory specifically set aside for record storage. The number of records that may be stored by the relay is dependent upon the selected recording duration:
Total number of records available in disturbance recorder is:
o One — for set Max Record Time from in range: 1.51s — 3s
o Two – for set Max Record Time from in range: 1.01s – 1.5s
o Three – for set Max Record Time from in range: 0.76s — 1s
o Four – for set Max Record Time from in range: 0.61s – 0.75s
o Five — for set Max Record Time from in range: 0.10s – 0.6s
The recorder stores actual samples that are taken at a rate of 16 samples per cycle. Each disturbance record consists of eight analog data channels and thirty-two digital data channels. The relevant CT and VT ratios for the analog channels are also extracted to enable scaling to primary quantities.
Note: If a CT ratio is set to less than a unit, the relay will choose a scaling factor of zero for the appropriate channel.
The «DISTURBANCE RECORDER» menu column is shown in the following table:
Menu Text Default Setting Setting Range

Post-Fault Time 0.1 s 0.1 s 2 s 0.01 s
Setting for the disturbance record post-fault time. The total disturbance recording time is: pre-fault time + high state of triggering criteria (Start or Trip time)+ post-fault time. The above total recording time is limited by setting.
Disturbance Rec.Trig. 0: on Inst. 0: on Inst. 1: on Trip
Setting for the trigger criteria: 0: on Inst. – the trigger is the disturbance indicated by the starting of a protection element set to trip the CB. If this option is chosen the total recording time is: pre-fault time + duration of protection start + post-fault time, but no longer than the value of Max Record Time. 1: on Trip. – the trigger is the disturbance indicated by the protection element trip. If this option is chosen the total recording time is: pre-fault time + duration of protection trip+ post-fault time, but no longer than the value of Max Record Time.
Max Record Time 1.0 s 0.1 s 3 s 0.01 s
Setting for the maximum total recording time. If default value is kept (3 s) it means that 2 records will be recorded.
It is not possible to display the disturbance records locally on the LCD; they must be extracted using suitable software such as MiCOM S1 or MiCOM S1 Studio.

INTRODUCTION
The MiCOM P111Enh feeder protection relays are fully numerical in design, implementing all protection and non-protection functions in software. The relays employ a high degree of self-monitoring. The commissioning tests do not need to be as extensive as with non-numeric electronic or electro-mechanical relays.
In the commissioning of numeric relays, it is only necessary to verify that the hardware is functioning correctly and that the application-specific software settings have been applied to the relay. It is considered unnecessary to test every function of the relay if the settings have been verified by one of the following methods:
• Extracting the settings applied to the relay using appropriate setting software (preferred method)
• Via the operator interface
Unless previously agreed to the contrary, the customer will be responsible for determining the application-specific settings applied to the relay and for testing of any scheme logic applied by external wiring.
Blank commissioning test and setting records are provided at the end of this chapter for completion as required.
BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE SAFETY GUIDE SFTY/4L M/E11 OR LATER ISSUE, OR THE SAFETY AND TECHNICAL DATA SECTION OF THE TECHNICAL MANUAL AND ALSO THE RATINGS ON THE EQUIPMENT RATING LABEL.
For safety reasons, no work must be carried out on the P111Enh until all power sources to the unit have been disconnected.
1. SETTING FAMILIARIZATION When commissioning a MiCOM P111Enh relay for the first time, sufficient time should be allowed to enable the user to become familiar with the method by which the settings are applied.
The Getting Started chapter (P111Enh/EN GS) contains a detailed description of the P111Enh relay.
Via the front panel all the settings can be changed (refer to Settings chapter P111Enh /EN ST of this manual), LEDs and alarms reset, and fault and event records cleared. However, menu cells with access levels higher than the default level will require the appropriate password to be entered, before changes can be made.
Alternatively, if a portable PC is available together with suitable setting software (such as MiCOM S1 or S1 Studio), the menu can be viewed a page at a time to display a full column of data and text. This PC software also allows settings to be entered more easily, saved to a file on disk for future reference or printed to produce a setting record. Refer to the PC software user manual for details (refer to Getting Started P111Enh /EN GS). If the software is being used for the first time, allow sufficient time to become familiar with its operation.

2. EQUIPMENT REQUIRED FOR COMMISSIONING 2.1 Minimum equipment required
Multifunctional dynamic current injection test set.
Multimeter with suitable ac current range.
Ensure that the multimeter fuse is not open-circuited if used for CT current measurement.
Multimeter with maximum value recording of the dc voltage (to measure the dc magnitude of the trip pulse)
Continuity tester (if not included in multimeter).
Note: Modern test equipment may contain many of the above features in one unit.
3. PRODUCT CHECKS These product checks cover all aspects of the relay and should be carried out to ensure that the unit has not been physically damaged prior to commissioning, that it is functioning correctly and that all input quantity measurements are within the stated tolerances.
If the application-specific settings have been applied to the relay prior to commissioning, it is advisable to make a copy of the settings to allow their restoration later. This could be done by:
• Obtaining a setting file from the customer.
• Extracting the settings from the relay itself (this again requires a portable PC with appropriate setting software)
• Manually creating a setting record. This could be done using a copy of the setting record located at the end of this chapter to record the settings. As the relay’s menu is scrolled through sequentially via the front panel user interface.
3.1 With the relay de-energized
The following group of tests should be carried out without powering the P111Enh.
The current transformer connections must be isolated from the relay for these operations to be carried out.
WARNING: NEVER OPEN CIRCUIT THE SECONDARY CIRCUIT OF A CURRENT TRANSFORMER SINCE THE HIGH VOLTAGE PRODUCED MAY BE LETHAL AND COULD DAMAGE INSULATION.
The line current transformers should be short-circuited and disconnected from the relay terminals. If this is not possible to complete this operation, the wiring to these circuits must be disconnected and the exposed ends suitably short-circuited to prevent a safety hazard.
3.1.1 Visual inspection
The rating information given under the top access cover on the front of the relay should be checked. Check that the relay being tested is correct for the protected line/circuit. Ensure that the circuit reference and system details are entered onto the setting record sheet. Double-check the CT primary current rating, and be sure to record the actual CT setting used.
Carefully examine the relay to check that no physical damage has occurred since installation.
3.1.2 Insulation
Insulation resistance tests are only necessary during commissioning and if they have not been performed during installation.
Commissioning
P111Enh_EN_CM v1.3 MiCOM P111Enh (CM) 8-5
CM
Isolate all wiring from the earth and test the insulation with an electronic or brushless insulation tester at a dc voltage not exceeding 500V. Terminals of the grouped circuits should be temporarily connected together.
The main groups of relay terminals are:
Current transformer circuits,
Auxiliary voltage supply
Binary control inputs
Relay contacts
EIA(RS)485 communication port
The insulation resistance should be greater than 100 MΩ at 500 V.
On completion of the insulation resistance tests, ensure all external wiring is correctly reconnected to the relay.
3.1.3 External wiring
Check that the external wiring is correct when compared to the relevant relay and scheme diagram. Ensure as far as practical that the phase sequence is as expected. The relay diagram number appears on the rating label on the upper side of the case.
The connections should be checked against the scheme (wiring) diagram.
3.1.4 Auxiliary supply voltage (Vx)
The relay can be operated from either a dc only or AC/DC auxiliary supply depending on the relay’s nominal supply rating. The incoming voltage must be within the operating range specified in Table 1.
Without energizing the relay measure the auxiliary supply to ensure it is within the operating range.
Nominal Supply Rating DC [AC r.m.s.]
DC Operating Range

24 — 60 V [24 — 60 V] 19 to 72 V 19 to 66 V A. B, E
90 — 250 V [90 — 240 V] 48 to 300 V 48 to 264 V
Table 1: Operational range of auxiliary supply Vx
It should be noted that the relay can withstand an ac ripple of up to 12% of the upper rated voltage on the dc auxiliary supply.
Do not energize the relay or interface unit using the battery charger with the battery disconnected as this can irreparably damage the relay’s power supply circuitry.
Energize the relay only if the auxiliary supply is within the specified operating ranges. If a test block is provided, it may be necessary to link across the front of the test plug to connect the auxiliary supply to the relay.
Note: Vx nominal supply rating is common to auxiliary voltage supply and binary control inputs
3.2 With the relay energized
The following group of tests verifies that the relay hardware and software are functioning correctly and should be carried out while the P111Enh is powered.
MV isolators should be opened and the MV side should be connected to the earth to allow safe operation of the CB.

3.2.1 Light emitting diodes (LEDs)
On power up the green LED should have lit up and stayed on indicating that the relay is healthy. The relay has a non-volatile memory that remembers the state (on or off) of the alarm, trip and, if configured to latch, LED indicators when the relay was last energized from an auxiliary supply. Therefore these indicators may also lit up when the auxiliary supply is applied.
Latching of LEDs can be configured via MiCOM S1 setting software (USB port) or manually by the front panel
Default configuration of LEDs (except Trip LED): without latching
Note: The above default configuration can be changed using the MiCOM S1 setting software (USB port).
Trip LED is fixed to protection trip with latching.
The eight LEDs are on the front panel of the relay:
• The green Healthy LED indicates that the P111Enh is powered and no internal faults are detected. A flashing LED indicates a hardware problem on the P111Enh. Not lit – P111Enh has no power supply
• Red Trip LED: indicates that the time-delay of the protection element set to trip has elapsed
• Yellow Alarm LED: indicates that the time-delay of the protection element set to Alarm has elapsed or that non-protection functions as issued an Alarm signal. This LED can be programmed as 3-7 LEDs too. Note: By default Alarm LED is not configured to Alarm. It is necessary to configure this LED for Alarm function via MiCOM S1 setting software (USB port) or manually by the front panel
The red LEDs 2 to 7 are programmable to the following signals:
Protect.Trip – Trip by protection elements

After establishing the connection between PC and P111Enh via the USB port, the green Healthy LED should be lit permanently (it means that the P111Enh is powered), even if P111Enh is not connected to auxiliary voltage supply.
The remaining LEDs can be checked via the “LEDs Reset” function. This function can be mapped to the L1 – L8 inputs.
Check that the correct nominal voltage and polarity are applied to opto inputs L1 – L6 (D1 — D10 terminals), then connect the field voltage to the appropriate terminals for the input being tested.
All red LEDs should be lit within 1 s.

3.2.2 Binary Inputs
This test checks that all the binary inputs on the relay are functioning correctly.
The binary inputs should be energized one at a time, see external connection diagrams (P111Enh/EN IN) for terminal numbers.
The P111Enh is fitted with an LCD display which makes it possible to view the state of the binary inputs, in the COMMISSIONING/Opto I/P Status menu cell. This information is also available via the MiCOM S1/S&R Modbus/ Measurement Viewer software. Refer to MiCOM S1 user manual for details.
If it is not possible to use the Measurement Viewer software, it is necessary to check the binary inputs by means of a functional test of the entire configuration.
Check that the correct nominal voltage and correct polarity are applied to the opto-inputs, then connect the field voltage to the appropriate terminals for the input being tested.
Note: The binary inputs may be energized from an external DC auxiliary supply (e.g. the substation battery) in some installations. Check that this is not the case before connecting the field voltage, otherwise damage to the relay may result. If an external 24/27 V, 30/34 V, 48/54 V, 110/125 V, 220/250 V supply is being used it will be directly connected to the relay’s optically isolated inputs. If an external supply is being used then it must be energized for this test but only if it has been confirmed that it is suitably rated with less than 12% AC ripple.
Default factory settings:
— L1 binary input (ABE): not configured
— L2 binary input (ABE): not configured
— L3 binary input(ABE): not configured
— L4 binary input(ABE): not configured
— L5 binary input (E): not configured
— L6 binary input( E): not configured
— L5 binary input (E): not configured
— L6 binary input (E): not configured
Reverse Input Logic indicates the low state of the Binary Input triggered by a programmable function.
3.2.3 Output Relays
To check output contacts it is necessary to carry out a functional test of the entire configuration.
Note: It should be ensured that thermal ratings of anything connected to the output relays during the contact test procedure are not exceeded by the associated output relay being operated for too long. It is therefore advised that the time between application and removal of the contact test is kept to the minimum.
Default factory settings:
— RL1-RL6 outputs: not configured
Reverse Output Logic means that after powering the P111Enh, n/o contacts are closed. Output triggering via a programmable function opens the contacts (rest position).
3.2.4 Rear Communications Port
This test should only be performed where the relay is to be accessed from a remote location and will vary depending on the communications standard adopted.
Commissioning

It is not the intention of the test to verify the operation of the complete system from the relay to the remote location, just the relay’s rear communications port and any protocol converter necessary.
3.2.4.1 IEC60870-5-103 (VDEW) communications
IEC60870-5-103/VDEW communication systems are designed to have a local Master Station and this should be used to verify that the relay’s EIA(RS)485 port, is working.
The relay address and baud rate settings for EIA(RS)485 can be set by using local communication via the USB port (setting software) or via the relay’s front panel.
Default Factory Setting:
— Baud Rate: 19.2 bps
— Parity: No parity
— Stop Bits: one stop bit
— Data Bits: 8 (fixed)
Also ensure that the relay’s address and baud rate settings in the application software are the same as those set via the USB port.
Check that, using the Master Station, communications with the relay can be established.
3.2.4.2 MODBUS communications
Connect a portable PC running the appropriate MODBUS Master Station software to the relay’s first rear EIA(RS)485 port via an EIA(RS)485 to EIA(RS)232 interface converter. The terminal numbers for the relay’s EIA(RS)485 port are up to 31.
The relay address, Parity and Baud Rate settings for EIA(RS)485 are set by using local communication via USB port (MiCOM S1 software).
Default Factory Setting:
— Baud Rate: 19.2 bps
— Parity: No parity
— Stop Bits: one stop bit
— Data Bits: 8 (no settable)
Ensure that the relay’s address and baud rate settings in the application software are the same as those set via the USB port.
Check that communications with the relay can be established.
3.2.5 USB communications port
The USB port is used for local communications between a PC and the P111Enh.
Note: Max current necessary to supply P111Enh from USB port is 450mA. USB standard offers 500mA for a one PC’s USB controller, so it is not recommended to connect any additional devices to the same PC’s USB controller. If the total power consumption from a one PC’s USB controller is greater than 500mA, P111Enh can be in permanent rest (P111Enh display and the green Healthy LED will be flashing)
The USB port integrates electronic boards only to allow communications with the P111Enh via the HMI and USB interfaces. Input (binary and current) and Output boards are not supplied.
For local communications, the MiCOM S1 setting software is used.
USB parameters (not settable in the P111Enh):
— Protocol: Modbus RTU
— Address: 1

3.2.6 Current inputs
This test verifies that the accuracy of current measurement is within the acceptable tolerances.
The P111Enh measures the RMS and Fundamental harmonic values.
Apply a current equal to the rating of the line current transformer secondary winding to each current transformer input of the corresponding rating, in turn (see Table 1 or external connection diagram (P111Enh/EN IN) for appropriate terminal numbers), checking its magnitude using a multimeter/test set readout. The corresponding reading can then be checked in the MEASUREMENT column of the menu or via the MiCOM S1/S&R Modbus/Measurement Viewer connected to the P111Enh via USB port. Refer to the PC software user manual for details.
If MiCOM S1 is not available, it is necessary to test the protection stages to measure the accuracy of analogue inputs.
Measuring accuracy of the relay:
Reference Conditions:
Sinusoidal signals with nominal frequency fn total harmonic distortion = 2 %, ambient temperature 20 °C and nominal auxiliary voltage Vx.
Deviation relative to the relevant nominal value under reference conditions.
Operating Data
For currents up to 2 In (Ien):
Phase and earth current: ±2% at In (Ien)
Asymmetry current: ±5% at In
Fault Data
Phase and earth current:
For currents ≤ 3 In (Ien): ±5% at In (Ien)
For currents > 3 In (Ien): ±5% of measured current value
However, an additional allowance must be made for the accuracy of the test equipment being used.

4. SETTING CHECKS The setting checks ensure that all of the application-specific relay settings (i.e. the relay’s functions), for the particular installation, have been correctly applied to the relay.
Note: The trip circuit should remain isolated during these checks to prevent accidental operation of the associated circuit breaker.
4.1 Apply application-Specific Settings
There are two methods of applying the settings to the relay:
Downloading them from a pre-prepared setting file to the relay using a portable PC running the MiCOM S1 support software. Communication between the PC and the P111Enh is done via the relay’s USB front port, located at the bottom of front panel, or rear communications port. This method is preferred for transferring function settings as it is much faster and there is less margin for error.
If a setting file has been created for the particular application and is available on an external memory disk, this will further reduce the commissioning time.
Enter them manually via the relay’s operator interface.
Application notes for the setting values are given in Application Notes chapter P111Enh/EN AP of this manual.
4.2 Demonstrate correct relay operation
The above tests have already demonstrated that the relay is within calibration, thus the purpose of these tests is as follows:
− To determine that the primary protection functions of the relay, overcurrent, earth-fault etc. can trip according to the correct application settings.
− by monitoring the response to a selection of fault injections.
4.2.1 Overcurrent protection testing
This test, performed on stage 1 of the overcurrent protection function, demonstrates that the relay is operating correctly at the application-specific settings.
4.2.1.1 Connection and preliminaries
The testing current is fed via terminals: C5-C6, C7-C8, and C9-C10, C11-C12 connected to CTs. The type of connection is shown in Figure 1. The external connection diagram is also available for the P111Enh front panel.
Ensure that I> is mapped to the RL1 output.
Connect the auxiliary voltage supply to the P111Enh’s terminals A1 and A2.
Connect the trip output RL1 to trip circuit of CB so that its operation will trip the test set and stop the timer.
The timer should be compatible with the RL1 output.
Connect the current output of the test set to phase “A” of the relay current transformer input (terminals C5 and C6).
Ensure that the timer starts when the current is applied to the relay.

4.2.1.2 Perform the test
Ensure that the timer is reset.
Apply to the relay a current of twice the setting for I> (refer to chapter P111Enh/EN ST of this manual) and make a note of the time displayed when the chronometer stops.
WARNING: Never open circuit the secondary circuit of a current transformer since the high voltage produced may be lethal and could damage insulation.
4.2.1.3 Check the Operating Time
Check that the operating time recorded by the timer is within the range shown in Table 2.
Notes: Except for the definite time characteristic, the operating times given in Table 2 are for a time multiplier or time dial setting of 1. Therefore, to obtain the operating time at other time multiplier or time dial settings, the time given in Table 2 must be multiplied by the setting for IDMT characteristics.
In addition, for definite time and inverse characteristics there is an additional delay of up to 0.03 seconds that may need to be added to
For all characteristics, allowance must be made for the accuracy of the test equipment being used.

5. FUNCTIONAL TESTS MiCOM P111Enh has special functions for this purpose available in COMMISIONING column.
In Model A and E the special function Maintenance Mode is available for more comfortable testing of the relay.
Note: If Maintenance Mode is not selected all test cells are hidden in P111Enh menu.
It is possible to set following Maintenance mode options (settings):
• “No” — Maintenance mode is disabled. All window cells below are hidden (Maintenance mode is the latest cell in COMMISIONING column)
• “Yes,outp.trips” — Maintenance mode is enabled. In this mode all test cells in COMMISIONING column are shown. During tests outputs are energized.
• “Yes,outp.block” — Maintenance mode is enabled and all test cells in COMMISIONING column are shown. In this mode, the high state of output functions are ignored (control of outputs are blocked).
This option allows the user to check the operation of the protection functions without actually sending any external command (Tripping or signalling).
Depends on the rear protocol selected in menu, transmission of information to SCADA is blocked (Modbus RTU) or sent (IEC 103) with additional information to know that P111Enh is in Maintenance mode (refer to Communication chapter and EN 60870-5-103 standard).
Changing of setting from “No” to “Yes,….” from the front panel activate this mode for 10 minutes only. After this time the option is automatically switched to “No”.
The selection of the maintenance mode is possible by logic input (the level), control command (rear or front port), or by front panel interface. The maintenance mode is terminated by:
• Low state of logic input assigned to Maintenance mode function,
• Control command which activate this mode (rear command or setting: “Yes,….”) and by turning off the power supply.
Note: Maintenance rear command is available in Modbus protocol only
Maintenance Mode 1: Yes,outp.trips
When this menu is activated (set to YES: “Yes,outp.trips” or “Yes,outp.block”), the Alarm led is lit.
In “Yes,outp.block” case, all the output contacts are blocked, and no command can be issued to these contacts, even if a protection threshold associated with one of these output contacts has been crossed. (If a protection threshold is crossed, all associated LEDs will be ON, even the TRIP LED, if protection element is set to Trip).
The commissioning cells allow the user to check the external wiring to the relay’s output contacts. This function is available after activation of Maintenance mode. To do this, the user has only to set to 1 the desired output contact’s corresponding bit, and this will close the contact and allow the continuity of the wiring to be checked.

In the cell below, the contact test time can be set:
Contact Test Time 001.00s
If the outputs for test are selected and Time for output closing is set, the closing command can be executed in this cell:
Test output 0: no operation
To execute the test, press OK key, press the or key to select 1: Apply test and confirm action by OK. The contact will be closed for the duration of the Contact Test Time pulse.
The next commissioning cells, which appears in Maintenance mode, allows the user to check the functional output configuration of the P111Enh. To do this, the user has only to select which protection element will be triggered, and this will close the contact assigned to this protection element and allow the continuity of the wiring to be checked.
Functional Test 0: I>
In the cell below the end of the functional test can be configured:
Functional Test End 0: CB trip
The following options are possible:
— 0: CB trip – after triggering the functional test, the test is interrupted after trip command.
— 1: Time – the protection element will be triggered for the duration of the pulse time.
If the 1: Time option is selected it is necessary to set the pulse length:
Contact Test Time 001.00s
The next cell is used for functional test execution:
Functional Test CTRL: no operation
To execute this test, press the OK key, press the or key to select 1: Operate and confirm action by pressing OK. The contact will be closed for the duration of the Contact Test Time pulse.

Maintenance
1.1 Maintenance period
It is recommended that products supplied by SCHNEIDER ELECTRIC ENERGY receive periodic monitoring after installation. In view of the critical nature of protective relays and their infrequent operation, it is desirable to confirm that they are operating correctly, at regular intervals.
SCHNEIDER ELECTRIC ENERGY protective relays are designed for a life in excess of 20 years.
MiCOM relays are self-monitoring and so require less maintenance than earlier designs of relay. Most problems will set off an alarm so that remedial action can be taken. However, some periodic tests should be carried out to ensure that the relay is functioning correctly and that the external wiring is intact.
1.2 Maintenance checks
Although some functionality checks can be performed from a remote location by utilizing the communications ability of the relays, these are predominantly restricted to checking that the relay is measuring the applied currents accurately. Therefore it is recommended that maintenance checks are performed locally (i.e. at the substation itself).
Before carrying out any work on the equipment, the user should be familiar with the contents of the Safety Guide SFTY/4L M/E11 or later issue, OR the safety and technical data section of the technical manual and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P111Enh until all power sources to the unit have been disconnected.
1.2.1 Binary Inputs
Binary inputs can be checked to ensure that the relay responds to its energization by repeating the commissioning test detailed in section 3.2.3 of the Commissioning chapter (P111Enh/EN CM).
1.2.2 Outputs
Output relays’ operation can be checked by repeating the commissioning test detailed in section 3.2.4 of the Commissioning chapter (P111Enh/EN CM).
1.2.3 Measurement Accuracy
If the power system is energized, the values measured by the relay can be compared with known system values to check that they are in the approximate expected range.. If they are, then the analogue/digital conversion and calculations are being performed correctly by the relay. Suitable test methods can be found in sections 3.2.7 of the Commissioning chapter (P111Enh/EN CM).
Alternatively, the values measured by the relay can be checked against known values injected into the relay via the test block, if fitted, or injected directly into the relay terminals. These tests will prove the calibration accuracy is being maintained.
P111Enh_EN_MT v1.3
Maintenance (MT) 9-4 MiCOM P111Enh
MT
1.3 Method of Repair
It is recommended that the P111Enh relay is returned to an SCHNEIDER ELECTRIC ENERGY service centre for repair.
Before carrying out any work on the equipment, the user should be familiar with the contents of the Safety Guide SFTY/4L M/E11 or later issue, OR the safety and technical data section of the technical manual and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P111Enh until all power sources to the unit have been disconnected.
1.4 Cleaning
Before cleaning the equipment ensure that all current transformers and voltage input connections are isolated to prevent any possibility of an electric shock whilst cleaning.
The equipment may be cleaned using a lint-free cloth moistened with clean water. The use of detergents, solvents or abrasive cleaners is not recommended as they may damage the relay’s surface and leave a conductive residue.

1. INTRODUCTION
BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE SAFETY GUIDE SFTY/4L M/E11 OR LATER ISSUE, or THE SAFETY AND TECHNICAL DATA SECTION OF THE TECHNICAL MANUAL AND ALSO THE RATINGS ON THE EQUIPMENT RATING LABEL.
For safety reasons, no work must be carried out on the P111Enh until all power sources to the unit have been disconnected.
The purpose of this section of the service manual is to allow an error condition on the relay to be identified so that appropriate corrective action can be taken.
In cases where a faulty relay is being returned to the manufacturer or one of their approved service centers, a completed copy of the Repair/Modification Return Authorization Form located at the end of this section should be included.
2. INITIAL PROBLEM IDENTIFICATION Consult the table below to find the description that best matches the problem experienced, then consult the section referenced to perform a more detailed analysis of the problem.

3. POWER UP ERRORS P111Enh can be powered up using the following power sources:
• USB connection to PC (function not available in Miodel L and N)
• Auxiliary voltage (Vx)
If the relay does not appear to power up then the following procedure can be used to determine whether the fault is in the external wiring or in the power supply module of the relay.
Test Check Action
1
1. Connect the P111Enh to a PC via the USB port.
2. Disconnect the PC from the P111Enh USB port.
(i) If the green “Healthy” LED and display are lit then proceed to test 2.
(ii) If the green “Healthy” LED and display are not lit then proceed to test 2.
2
1. Apply a Vx auxiliary voltage on terminals A1-A2 (check the level on the P111Enh nominal label)
2. Check whether the green “Healthy” LED on the P111Enh front panel is lit.
3. Disconnect the ac auxiliary voltage from terminals A1-A2.
(i) If the green “Healthy” LED and display are lit then proceed to test 3.
(ii) If the green “Healthy” LED and display are not lit then send the relay back to Schneider Electric Energy’s repair centre.

4. MALOPERATION OF THE RELAY DURING TESTING 4.1 Failure of Binary Inputs (A, B and E only)
The binary inputs are configured in the SETTING GROUPx/INPUTS CONFIGURATION column for each setting group. If an input does not appear to be recognized by the relay scheme logic the COMMISSIONING/Opto I/P Status menu option can be used to verify whether the problem is in the binary input itself or the mapping of its signal to the scheme logic functions. If the binary input appears to be read correctly then it is necessary to examine its configuration.
Ensure the voltage rating for the opto inputs has been configured correctly with applied voltage. If the binary input state is not read correctly by the relay the applied signal should be tested. Verify the connections to the binary input using the correct wiring diagram. Next, using a voltmeter verify that 80% opto setting voltage is present on the terminals of the binary input in the energized state. If the signal is being correctly applied to the relay then the failure may be on the input card itself.
Notes: 1. If the P111Enh is exclusively powered from the USB port, only some of the relay’s electronic circuits (necessary for communications) are supplied. For this reason, inputs are in high state (independent of the voltage at the terminals). Any action pertaining to binary inputs is blocked.
2. Only the logical state of the inputs is given in the COMMISSIONING /Opto I/P Status cell, not presence of voltage at the terminals. For example: If Vx (high state) and Reverse Input Logic are set (function active in low state of binary input) at the terminals of a binary input in the COMMISSIONING /Opto I/P Status cell, the logical state of the input is low (logical status after application of the Reverse Input Logic function).
4.2 Failure of Output Contacts
An apparent failure of the relay’s output contacts may be caused by the relay configuration; the following tests should be performed to identify the real cause of the failure. Tests of outputs can be performed using the COMMISSIONING/Test outputs cell. The command is executed and the configured outputs (COMMISSIONING/Test Pattern) will be energized for the duration of Contact Test Time (COMMISSIONING).
Test Check Action
1
Is the Out of Service LED illuminated?
Illumination of this LED may indicate that the relay is in test mode or that the protection has been disabled due to a hardware verify error (see Table 2).
2 Examine the Test outputs (AE) in the Commissioning section of the menu.
If the relevant bits of the contact status are operated then proceed to test 4, if not proceed to test 3.
3
Verify by examination of the fault record whether the protection element is operating correctly.
If the protection element does not operate verify whether the test is being correctly applied. If the protection element operates then it is necessary to check the configuration, to ensure that the configuration of the protection element to the contacts is correct.
4
Using the procedure described in the Commissioning chapter (P111Enh/EN CM) energize every output (note the correct external connection diagram should be consulted). A continuity tester can be connected at the rear of the relay for this purpose.
If the output relay operates then the problem must be situated in the external wiring to the relay. If the output relay does not operate this could indicate a failure of the output relay contacts (note that the self-tests verify that the relay coil is being energized). Ensure that the closed resistance is not too high for the continuity tester to detect.

1. RECEIPT OF RELAYS Upon receipt, relays should be examined immediately to ensure no external damage has been sustained in transit. If damage has been sustained, a claim should be made to the transport contractor and Schneider Electric Energy should be promptly notified.
Relays that are supplied unmounted and not intended for immediate installation should be returned to their protective polythene bags and delivery carton. Section 3 of P111Enh/EN IN gives more information about the storage of relays.
2. HANDLING OF ELECTRONIC EQUIPMENT A person’s normal movements can easily generate electrostatic potentials of several thousand volts. Discharge of these voltages into semi-conductor devices when handling electronic circuits can cause serious damage that, although not always immediately apparent can reduce the reliability of the circuit. The relay’s electronic circuits are protected from electrostatic discharge when housed in the case. Do not expose them to risk by removing the front panel or printed circuit boards unnecessarily.
Each printed circuit board incorporates the highest practicable protection for its semi-conductor devices. However, if it becomes necessary to remove a printed circuit board, the following precautions should be taken to preserve the high reliability and long life for which the relay has been designed and manufactured.
Before removing a printed circuit board, ensure that you are at the same electrostatic potential as the equipment by touching the case.
Handle analog input modules by the front panel, frame or edges of the circuit boards. Printed circuit boards should only be handled by their edges. Avoid touching the electronic components, printed circuit tracks or connectors.
Do not pass the module to another person without first ensuring you are both at the same electrostatic potential. Shaking hands achieves equipotential.
Place the module on an anti-static surface, or on a conducting surface that is at the same potential as you.
If it is necessary to store or transport printed circuit boards removed from the case, place them individually in electrically conducting anti-static bags.
In the unlikely event that you are making measurements on the internal electronic circuitry of a relay in service, it is preferable that you are earthed to the case with a conductive wrist strap. Wrist straps should have a resistance to ground between 500 kΩ and 10 MΩ. If a wrist strap is not available you should maintain regular contact with the case to prevent a build-up of electrostatic potential. Instrumentation which may be used for making measurements should also be earthed to the case whenever possible.
More information on safe working procedures for all electronic equipment can be found in BS EN 100015: Part 1:1992. It is strongly recommended that detailed investigations on electronic circuitry or modification work should be carried out in a special handling area such as described in the British Standard document.
3. STORAGE If relays are not to be installed immediately upon receipt, they should be stored in a place free from dust and moisture in their original cartons. Where de-humidifier bags have been included in the packing they should be retained.
Care should be taken on subsequent unpacking that any dust, which has collected on the carton, does not fall inside. In locations of high humidity the carton and packing may become impregnated with moisture and the de-humidifier crystals will lose their efficiency.
Prior to installation, relays should be stored at a temperature of between –25°C to +70°C (-13°F to +158°F).

4. UNPACKING Care must be taken when unpacking and installing the relays so that none of the parts are damaged and additional components are not accidentally left in the packing or lost. Ensure that any User’s CD ROM or technical documentation is NOT discarded – this should accompany the relay to its destination substation.
Relays must only be handled by qualified persons.
The site should be well lit to facilitate inspection, clean, dry and reasonably free from dust and excessive vibration.
5. RELAY MOUNTING Individual relays are normally supplied with an outline diagram showing the dimensions. This information can also be found in the product publication.
Flush mounted version: Make a cut-out in mounting plate according to fig. 1. Then insert the relay into it. Fit fastening elements (see fig. 1) into the slots in the sides of the housing, and keep turning the fastening screws until the relay is securely fixed to the plate. To remove the relay undo the screws, so that the fastening element could be taken out, and then the relay could be withdrawn from the cut-out in the mounting plate.
Mounting on the wall:
Flush mounting case of P111Enh can be mounted on the wall by using optional Wall Mounting Case Adaptor (ordering number: REL10030)
Insert the relay into wall mounting adaptor according to fig. 2. Fit fastening elements (see fig. 2) into the slots in the sides of the housing, and keep turning the fastening screws until the relay is securely fixed to the wall mounting adaptor. To remove the relay undo the screws, so that the fastening element could be taken out, and then the relay could be withdrawn from the wall mounting adaptor.
6. RELAY WIRING
BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE SAFETY GUIDE SFTY/4L M/E11 OR LATER ISSUE, OR THE SAFETY AND TECHNICAL DATA SECTION OF THE TECHNICAL MANUAL AND ALSO THE RATINGS ON THE EQUIPMENT RATING LABEL.
For safety reasons, no work must be carried out on the P111Enh until all power sources to the unit have been disconnected.
The measuring current inputs of the P111Enh should be connected to the secondary wires of the power system CTs as shown in the connection diagrams in section 8. ” External Connection Diagram” of this chapter P111Enh/EN IN.
The CT types which can be connected to the P111Enh’s current input terminals are shown in section 3 of the Applications chapter P111Enh/EN AP.

2. MODBUS PROTOCOL
MiCOM P111Enh relay can communicate by a RS 485 link behind the unit following the MODBUS MODICON RTU protocol.
2.1 Technical characteristics of the MODBUS connection
2.1.1 Parameters of the MODBUS connection
The different parameters of the MODBUS connection are as follows :
• Isolated two-point RS485 connection (2kV 50Hz),
• MODBUS MODICON line protocol in RTU mode
• Communication speed can be configured by an operator dialog in the front panel of the relay :
Baud rate
4800
9600
38400
57600
115200
Transmission mode of the configured characters by operator dialog:
Mode
1 start / 8 bits / 1 stop : total 10 bits
1 start / 8 bits / even parity / 1 stop : total 11 bits
1 start / 8 bits / odd parity / 1 stop : total 11 bits
1 start / 8 bits / 2 stop : total 11 bits
2.1.2 Synchronisation of exchanges messages
All character received after a silence on the line with more or equal to a transmission time of 3 characters is considered as a firm start.
2.1.3 Message validity check
The frame validity is working with a cyclical redundancy code CRC with 16 bits. The generator polynomial is:
1 + x² + x15 + x16 = 1010 0000 0000 0001 binary = A001h
Address of the MiCOM relays
The address of the MiCOM relay on a same MODBUS network is situated between 1 and 254. The address 0 is reserved for the broadcast messages

2.2 MODBUS functions of the MiCOM relays
The MODBUS functions implemented on the MiCOM relays are :
Function 3 or 4 : Reading of n words
Function 5 : Writing of 1 bit
Function 6 : Writing of 1 word
Function 7 : Fast reading of 8 bits
Function 16 : Writing of n words
2.3 Presentation of the MODBUS protocol
Master slave protocol, all exchange understands a master query and a slave response
Frame size received from MiCOM P111Enh Dual-powered relay
Frame transmitted by the master ( query) :
Slave number
Function code
Information CRC1 6
1 byte 1 byte n bytes 2 bytes
0 à FFh 1 à 10h
Slave number:
The slave number is situated between 1 and 254.
A frame transmitted with a slave number 0 is globally addressed to all pieces of equipment (broadcast frame )
Function code:
Requested MODBUS function (1 to 16)
Information:
Contains the parameters of the selected function.
CRC16:
Value of the CRC16 calculated by the master.
Note: The MiCOM relay does not respond to globally broadcast frames sent out by the master.

Data :
Contains reply data to master query .
CRC 16:
Value of the CRC 16 calculated by the slave.
2.3.2 Messages validity check
When MiCOM P111Enh relay receive a master query, it validates the frame :
• If the CRC is false, the frame is invalid. MiCOM P111Enh relay do not reply to the query. The master must retransmit its query. Excepting a broadcast message, this is the only case of non-reply by MiCOM P111Enh relay to a master query.
• If the CRC is good but the MiCOM relay can not process the query, it sends an exception response.
Warning frame sent by the MiCOM relay (response)
Slave number Function code Warning code CRC16
1 byte 1 byte 1 byte 2 bytes
1 to FFh 81h or 83h or 8Ah or 8Bh pf … PF
Slave number :
The slave number is situated between 1 and 254.
Function code :
The function code returned by the MiCOM relay in the warning frame is the code in which the most significant bit (b7) is forced to 1.
Warning code :
On the 8 warning codes of the MODBUS protocol, the MiCOM relay manages two of them :
• code 01 : function code unauthorised or unknown.
• code 03 : a value in the data field is unauthorised ( incorrect data ).

2.4.1.2 Disturbance Records
Before uploading any disturbance record, a service request must be send to select the record number to be uploaded.
The answer following this request contain the following information:
• Numbers of samples (pre and post time)
• Phase CT ratio
• Earth CT ratio
• Internal phase and earth ratios
• Number of the last disturbance mapping page
• Number of samples in this last disturbance mapping page
The mapping pages used for this service request are from 38h to 3Ch.
Pages 9h to 21h : Contain the disturbance data (25 pages)
A disturbance mapping page contains 250 words:
0900 to 09FAh : 250 disturbance data words 0A00 to 0AFAh : 250 disturbance data words 0B00 to 0BFAh : 250 disturbance data words
…… 2100 to 21FAh : 250 disturbance data words
The disturbance data pages contain the sample of a single channel from a record.
Page 22h : contains the index of the disturbance

2.4.1.3 Event records
To upload the event records two requests are allowed:
Page 35h: Request to upload an event record without acknowledge of this event.
Used addresses:
3500h : EVENT 1
….. 3563h : EVENT 100
Page 36h: Request to upload the non-acknowledged oldest stored event record.
Two modes are available for the acknowledgement: automatic acknowledgement or manual acknowledgement
The mode depends of the state of bit 12 of telecommand word (address 400 h).
If this bit is set, then the acknowledgement is manual else the acknowledgement is automatic.
In automatic mode, the reading of the event acknowledges the event.
In manual mode, it is necessary to write a specific command to acknowledge the oldest event
(set the bit 13 of control word 400 h )
2.4.1.4 Fault records
Page 37h: Page dedicated to upload fault record
Used addresses:
3700h : FAULT 1 3701h : FAULT 2
….. 3704h : FAULT 5
Page 3Eh: Request to upload the non-acknowledged oldest stored fault record.
Two modes are available for the acknowledgement: automatic acknowledgement or manual acknowledgement
The mode depends of the state of bit 12 of telecommand word (address 400 h).
If this bit is set, then the acknowledgement is manual else the acknowledgement is automatic.
In automatic mode, the reading of the fault acknowledges automatically the event.
In manual mode, it is necessary to write a specific command to acknowledge the oldest fault.
(set the bit 14 of control word 400 h )

3. IEC60870-5-103 INTERFACE
The IEC60870-5-103 interface is a master/slave interface with the relay as the slave device. This protocol is based on the VDEW communication protocol. The relay conforms to compatibility level 2, compatibility level 3 is not supported.
The following IEC60870-5-103 facilities are supported by this interface:
Initialisation (Reset)
Time Synchronisation
Event Record Extraction
General Interrogation
Cyclic Measurements
General Commands
Physical connection and link layer
Connection is available for IEC60870-5-103 through the rear RS485 port. It is possible to select both the relay address and baud rate using the front panel interface. Following a change, a reset command is required to re-establish communications.
The parameters of the communication are the following:
Even Parity
8 Data bits
1 stop bit
Data rate 9600 or 19200 bauds
Initialisation
Initialisation is implemented according to clause 7.4.1 of IEC 60870-5-103.
Whenever the relay has been powered up, or if the communication parameters have been changed a reset command is required to initialise the communications. The relay will respond to either of the two reset commands (Reset CU or Reset FCB), the difference being that the Reset CU will clear any unsent messages in the relay’s transmit buffer.
The relay will respond to the reset command with an identification message ASDU 5, the Cause Of Transmission COT of this response will be either Reset CU or Reset FCB depending on the nature of the reset command. The following information will be contained in the data section of this ASDU:
Manufacturer Name: SE MiCOM
According to the specification “Communication Architecture (ACA), Part 4: Communication based on IEC 60870-5-103” (Issue H, April 2010) the Software Identification Section will contain the relay model number and the version number to identify the type of relay.
Software Identification Section, Byte 0: Numerical part of device type, hex, low
Software Identification Section, Byte 1: Numerical part of device type, hex, low
Software Identification Section, Byte 2: Software version, hex, low
Software Identification Section, Byte 3: Software version, hex, high
Letters in the software version are converted to numerical values according to the following rule: A=0, B=1, C=2, D=3 etc.
The Software Identification Section of P111Enh, version 1A, will then contain ‘111’ and ‘10’ as hexadecimal coded values:
Communication Database
P111Enh_EN_CT v1.3 MiCOM P111Enh (CT) 13-59
CT
Byte 0: 74H
Byte 1: 00H
Byte 2: 10H
Byte 3: 00H
In addition to the above identification message, if the relay has been powered up it will also produce a power up event.
Time synchronisation
Time synchronisation is implemented according to clause 7.4.2 of IEC 60870-5-103.
The relay time and date can be set using the time synchronisation feature of the IEC60870-5-103 protocol. The relay will correct for the transmission delay as specified in IEC60870-5-103. If the time synchronisation message is sent as a send/confirm message then the relay will respond with a confirm. Whether the time synchronisation message is sent as a send confirm or a broadcast (send/no reply) message, a time synchronisation message will be returned as Class 1 data.
Spontaneous events
The events created by the relay will be passed to the master station using the compatible range and the private range of IEC 60870-5-103 function types and information numbers.
Events are categorised using the following information:
Common Address
Function Type
Information number
3.10-3.14 contains a complete listing of all events produced by the relay.
General interrogation
General interrogation is implemented according to clause 7.4.3 of IEC 60870-5-103.
The GI request can be used to read the status of the relay, the function numbers, information numbers and common address offsets that will be returned during the GI cycle are indicated in 3.10-3.14.
Cyclic measurements
The relay will produce measured values using ASDU 3 and ASDU 9 on a cyclical basis. They can be read from the relay using a Class 2 poll.
It should be noted that the measurands transmitted by the relay are sent as a proportion of 2.4 times the rated value of the analogue value. The selection of 2.4 for a particular value is indicated in 3.10-3.14.
Commands
Command transmission is implemented according to clause 7.4.4 of IEC 60870-5-103.
A list of the supported commands is contained in 3.10-3.14. The relay will respond to all other commands with an ASDU 1, with a cause of transmission (COT) of negative acknowledgement of a command
Blocking of monitor direction
The relay does not support a facility to block messages in the Monitor direction.

Spontaneous messages managed by MiCOM P111Enh
These messages includes a sub-assembly of events which are generated on the relay, because some generated events are not registered in VDEW. They are the most priority messages.
An event is always generated on the rising edge of the information.
Some events can be generated on the rising or lowering edge.
In the list below, events only generated on rising edge will be tagged with a ‘*’.
The following list of processed events contains the messages for the compatible and the private range.for all Overcurrent protection functions, with the associated FUNCTION TYPE, INFORMATION NUMBER, ASDU TYPE, CAUSE OF TRANSMISSION
FUN <160>: Function type in Public range for Overcurrent Protections (compatible).
FUN <162> ,<163>, <164>, <165>, <168>:: Function type in Private range (Reserved for Overcurrent Protections).

Processed Commands
System Commands:
Synchronization Command (ASDU 6): FUN<255>,INF <0>; TYP <6>;COT<8>
This command can be sent to a specific relay, or global. The time sent by master is the time of the first bit of the frame. The relay synchronizes with this time, corrected by the frame transmission delay. After updating its time, the relay send back an acknowledge to the master, by giving its new current time.
This acknowledge message will be an event of ASDU 6 type.
General Interrogation Initialization command (ASDU 7):
FUN<255>;INF <0>;TYP <7>; COT<9>
This command starts the relay interrogation:
The relay then sends a list of data containing the relay state (see list described above).
The GI command contains a scan number which will be included in the answers of the GI cycle generated by the GI command.
If a data has just changed before extracted by the GI, the new state is sent to the master station.
When an event is generated during the GI cycle, the event is sent in priority, and the GI cycle is temporarily interrupted. The end of the GI consists in sending an ASDU 8 to the master station.
If, during a General Interrogation cycle, another GI Initialization command is received, the precedent answer is stopped, and the new GI cycle started.
General Commands (ASDU 20) (Control direction): Availability
LED Reset and Sign. reset: This command reset LEDs, signaling: FUN<160>;INF<19>, TYP<20>, COT <20>,<ADDR>
In LED Reset control command the allowed value is:
DCO <0000 0010> «Reset»
Output Reset: This command reset Latched Outputs: FUN<162>;INF<46>, TYP<20>, COT <20>,<ADDR>
In Latched Outputs Reset control command the allowed value is:
DCO <0000 0010> «Reset»
Setting group number 1: FUN<160>;INF<23>, TYP<20>, COT <20>,<ADDR>
In Setting group number 1 control command the allowed value is:
DCO <0000 0010> «Set Group 1”
Setting group number 2: FUN<160>;INF<24>, TYP<20>, COT <20>,<ADDR>
In Setting group number 2 control command the allowed value is:
DCO <0000 0010> «Set Group 2”
Order Command 1: FUN<249>;INF <129>; COT<20>,<ADDR>
In Order Command 1 control command the allowed value is:

DCO <0000 0010> “ON”
CB control Open command : FUN<242>;INF <65>; TYP <20>; COT<20>,<ADDR>
In CB control command the DCO allowed values are:
DCO <0000 0001> “OFF”: «Close CB»
<0000 0010> “ON”: «Open CB»
CB control Close command FUN<242>;INF <66>; TYP <20>; COT<20>,<ADDR>
In CB control command the DCO allowed values are:
DCO <0000 0001> “OFF”:»Open CB»
<0000 0010> “ON”: «Close CB»
ARC: Enabled FUN<160>; INF<16>; COT<20>,<ADDR>
Note: ARC: Enabled is used for command and indication (see: Status indications in monitor direction Type Identification).
In ARC: Enabled command the DCO allowed values are:
DCO <0000 0001> «OFF»
<0000 0010> «ON»
General commands are processed according to clause 7.4.4 of IEC 60870-5-103.
After executing one of these commands, the relay sends an positive or negative acknowledge message, which contains the result of command execution.
If a state change is the consequence of the command, it must be sent in a ASDU 1 with COT 12 (remote operation).
If the relay receives another command message from the master station before sending the acknowledge message for the previous command, it will be discarded and a negative acknowledge message will be sent.
Commands which are not processed by the relay are rejected with a negative acknowledge message.
Relay re initialization
In case of relay re initialization, the relay send to the master station:
A message indicating relay start/restart (FUN<160>;INF <5>; TYP <5> COT <5>) or a message indicating Reset CU (FUN<160>;INF <5>; TYP <3> COT <4>) or a message indicating Reset FCB (FUN<160>;INF <5>; TYP <2> COT <3>)

Cyclic Messages (ASDU9 and ASDU3)
Only measurements can be stored in these messages.
The measured values are stored in lower levels of communication, before polling by master station.
Ia, Ib, Ic are transmitted with ASDU 9 (FUN<160>,INF<148>).
IN is transmitted with ASDU 3(FUN<160>,INF<147>).
All other measurments are unused in ASDU 3 and ASDU 9.
The values are stored with a rate of 2,4 * nominal value = 4096.
Thermal Overload value is transmitted with ASDU 3 (FUN<162>,INF<23>).
Scalling: 1% * value (range: 0-200)
