The PGR-6100 monitor combines the features of a ground-fault protection relay and insulation monitor into one unit. The monitor can detect a motor ground fault whether the motor is running (online mode) or stopped (offline mode). 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-6100 features two separate analog outputs for optional current and ohm meters and two separate alarm relays. The unit operates on one- or three-phase solidly grounded, resistance grounded, and ungrounded systems up to 6 kV. Selectable fail-safe or non-fail safe operating modes allow connections to shunt or undervoltage breaker coils. The PGR-6100 is unique in that it has predictive as well as protective capabilities.
