Megger ODEN AT Designed for Reliable Primary Current Injection Testing

Megger-ODEN-ATDuring primary current injection testing a test current is injected into the primary side of a system to determine how the system behaves at particular levels of current.
A common system that is regularly tested involves a circuit breaker with an over-current trip relay that operates via a current transformer (CT).  By injecting a predetermined current into the circuit breaker, it is possible to determine whether the relay will trip at this current and, if so, how long the current needs to flow before the trip is initiated.

The Megger ODEN AT is designed for primary current injection testing of protective relay equipment and circuit breakers.

The Megger ODEN AT Primary Current Injection Test System consists of a control unit together with one, two or three high current output modules.  

Protec is proud to offer the ODEN AT with a configurable output, making it suitable for applications of varying output requirements. 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 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.
