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.
Applications
Used on substations, motor control centers (MCCs), central
distribution panels, switchboards, and test benches to verify
relay operation.
It is recommended to test every relay annually as well as its
current interrupting device.
Features/Benefits
