GROUND FAULT & INSULATOR MONITOR
Description
The PGR-6101 combines the features of a ground-fault
protection relay and insulation monitor into one unit.
It protects against ground faults by monitoring insulation
resistance when the motor is de-energized and by monitoring
ground-fault current when the motor is energized. The
PGR-6101 features two separate analog outputs for optional
current and ohm meters, and two separate alarm relays. It
operates on one- or three-phase solidly grounded, resistance
grounded and ungrounded systems up to 6 kV.
