Relay Testers

Description

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.
