This powerful test system is designed for primary injection testing of protective relay equipment and circuit breakers.
It is also used to test the transformation 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
transformation ratio as well as time, voltage and current. A second measurement channel can be used to test 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 short-duration 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
