Test the turns ratio of current transformers and other applications that require high variable currents with the Megger ODEN AT Primary Current Injection Test System, Designed forprimary injection testing of protective relay equipment and circuit breakers, it can also be used on numerous other applications:
TheMegger ODEN AT Primary Current Injection Test Systemconsists of a control unit together with one, two or three high current output modules, and offers a configurable output, making it suitable for applications of varying output requirements.
The Megger ODEN AT Primary Current Injection Test Systemis a powerful test system 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.
During 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.
Primary Injection Test Sets are high current units designed for testing and adjusting low voltage circuit breakers and other current actuated devices. Typical test sets incorporate a variable high current ac output along with circuitry to measure the reactions of the breaker under test.
