The SE-400 is a ground fault relay test unit designed to test current pickup level, time delay and coordination of ground fault protection. The tester injects current through the window of installed ground fault current transformers to verify the operation of ground fault monitors and relays. It is used on substations, motor control centers (MCCs), central distribution panels, switchboards and test benches to verify relay operation. The SE-400 tests the entire ground fault circuit including current transformers, wiring, ground fault relay and the operation of the interrupting device. It is recommended to test every relay and its current interrupting device annually.
