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.
