Description
The PGM-8600 relay monitors the insulation resistance to
ground for failures. It provides two warnings, one alarm, and
an analog output for predictive maintenance. The relay can
operate on 1 or 3-phase grounded, resistance grounded or
ungrounded systems up to 6 kV. When the power system is
de-energized, the relay monitors the insulation for damage,
allowing for predictive maintenance and troubleshooting for
developing ground faults. When the power system is energized in
ungrounded systems, the relay continues to monitor the insulation.
In grounded systems, the relay switches off to prevent nuisance
tripping. The mode of operation terminals (27-28) are connected to
the circuit breaker or contactor auxiliary contacts to toggle the relay
off when the contactor or breaker is closed.
