PGT-0400 SERIES
Ground-Fault Relay Test Unit
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
?  The PGT-0400 tests the entire ground-fault circuit
including current transformers, wiring, ground-fault relay
and the operation of the interrupting device
?  Current range is 0.5 to 9.9 A
?  Duration range is 0.1 to 9.9 s or continuous output
?  Light weight and compact for portability
