Description
The PGT-0400 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.
Used on substations, motor control centers (MCCs), central
distribution panels, switchboards, and test benches to verify
relay operation.
The PGT-0400 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.
