Description
The SE-100T is a ground-fault-relay test unit designed to test
the current pickup level 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-100T 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.
