About Secondary Current Injection Test Sets

The secondary injection test simulates the current and voltage transformer secondaries, by injecting single-phase or three-phase currents and voltages into relays, and devices into the secondary circuits, performing all the corresponding checking and testing with normal and fault conditions. Can only be done on electronic breakers however less expertise is required to run the test.

The purpose is to verify that the correct operation of the protection scheme from the relay input terminals onward is functioning correctly with the settings specified. The secondary protection system consists of auxiliary relays, protective relays, protection circuits, metering devices, communications and control systems, low-voltage devices, etc.
