ODEN AT

Primary Current Injection Test System

ODEN AT

Primary Current Injection Test System

▪▪Most Advanced Primary Current Injection

Test System to simplify all types of switchgear and CT commissioning, ground grid, circuit breaker testing and more

▪▪Modular design to permit optimal user configuration of output current vs. unit size

▪▪Compact transport cart facilitates portability into switchgear rooms with limited space

▪▪Unique I/30 function allows the current to be pre-set using low current to prevent test sample heating, thus eliminating corruption of test result

Description

This powerful test system is designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the turns ratio of current transformers and for other applications that require high variable currents.

The system consists of a control unit together with one, two or three current units. There are three versions of the current unit: S, X and H. The S and X current units are identical except that the X unit has an additional 30/60 V output. The H unit is rated for even higher current. This makes it possible to configure an ODEN AT system in a suitable way. All parts are portable, and ODEN AT can be quickly assembled and connected.

The control unit has many advanced features – a powerful measurement section for example, that can display turns ratio as well as time, voltage and current. A second measurement channel can be used to measure an additional current or voltage. Current transformer turns ratio, impedance, resistance, power, power factor (cos φ) and phase angle are calculated and shown in the display. Current and voltage can be presented as percentages

of nominal value. The fast-acting hold function freezes shortduration readings on the digital display when the voltage or contact signal arrives at the stop input, the object under test interrupts the current or injection is stopped

Application

Primary current injection testing and breaker testing

These tests require high currents and the ability to measure very short duration, current flow. ODEN AT has been designed especially to meet these needs. No extra contacts are needed to measure the operating time of a low-voltage breaker. Testing stops at the instant when the main breaker contacts open to interrupt the current. Output current initiation is synchronized with the currents zero-crossover point to ensure good repeatability and minimized DC offset.

Testing current transformers

For turns ratio testing, the primary current and either the secondary current or the turns ratio are displayed simultaneously. Since the turns ratio is displayed directly as the nominal value (1000/5 for example), no further calculation is needed. Burden of secondary circuits can be measured and presented in VA.

Polarity testing

The currents phase displacement is shown, and the polarities of the outputs are clearly marked.

Heat runs

ODEN AT is ideal for performing heat runs. Current can be applied continuously or through programmable intervals. The times can be shown in minutes and hours which facilitates longterm testing capability.

Automatic reclosers and sectionalizers

ODEN AT can also be set to test circuit breakers with reclosing relays. Operating limits, partial times, total times and the number of operations before lockout can be measured. User-selectable reclosing sequences can be programmed for testing sectionalizers.

Testing integrity of ground grids and safety-ground devices

One way to test ground grids is by injecting current between a reference ground and the ground to be tested and measuring the voltage drop and the percentage of current flowing through the ground grid. The type X current unit included with ODEN AT is designed for this type of application. Personal safety grounds

must be tested at rated current, a task for which ODEN AT is well suited.

Features and Benefits

1.Display. The display presents time, output current, voltage, current shown on ammeter 2 and phase angle. You can scroll through entities Z, P, Q, R, X, S, power factor (cos φ) and I max.

2.Miniature circuit breaker used for current output. Interrupts output current. Can also be actuated manually for safe disconnection of load.

3.Current reduction button. Used during setting to reduce the output current to 1/30. Useful in order to avoid for example unintentional tripping and overheating.

4.Fine adjustment knob. Knob for fine adjustment of current and +/- buttons for coarse adjustment.

5.Indicator lamps. Indicate whether ammeter 2 or the voltmeter is enabled.

6.Input for voltmeter. Used to measure voltage and for microhmmeter measurement.

7.Input for ammeter 2. Used to measure current in an external circuit (in a current transformer´s secondary winding for example).

8.Hold function. This function freezes readings on the display.

9.Selection/setting (CHANGE) knob. Selects the desired menu option (shown in the display window). Also used to change numerical values.

10.Setting buttons. Personnel unfamiliar with ODEN AT can use the pre-defined settings very effectively, while experienced users can make their own basic settings.

•Ammeter. Used to set the main current-output ammeter. You can select the desired range or select autoranging.

•V/A Meter. Toggles between the voltmeter and ammeter 2. Also used to select the desired range or select autoranging.

•System. Used for general settings.

•Memory. Used to save or recall settings to or from the ten ODEN AT memories. One of these memories contains the default (pre-defined) settings that are invoked when ODEN AT is powered up.

ODEN AT

Primary Current Injection Test System

• Application. Used to invoke the desired measurement mode: automatic recloser, sectionalizer or microhmmeter.

ODEN AT can also be set to generate pulse trains with user-se- lectable pulse and pause times.

11.Injection. Starts current injection and timing.

12.Momentary Injection. When this button is used, injection continues only as long as it is pressed. Useful in order to avoid for example overheating.

13.RS232 for computer. ODEN AT is equipped with a serial port for communication with PC (for transfer of test data for example).

14.Manual shut-off. Injection and timing are stopped when this button is pressed.

15.Automatic injection stop. Generation stops after a user-spec- ified interval or when condition at the input is met. The diodes show the selected OFF condition.

16.Stop-condition indicator. Indicates that a stop condition is met, voltage or contact triggered.

17.Status indicator. Indicates if a contact connected to the input is closed or if voltage is present.

18.Stop input. Used to freeze a reading or stop injection. Activated when current is interrupted by the object being tested, when an external contact is actuated or when a voltage is applied or removed.
