PGR-3100 GROUND-FAULT INDICATION SYSTEM MANUAL
■The PGR-3100 is a self-powered ground-fault indication system. Presence of phase-to-ground voltage is indicated by redundant LEDs (two per phase). The respective phase LEDs are off when phase-to-ground voltage is less than 25 Vac for L terminals, and less than 40 Vac for H terminals. The PGR-3100 meets the National Electrical Code requirements for ground detectors for ungrounded alternating-current systems as defined in NEC 250.21. It also meets the Canadian Electrical Code requirements for ungrounded alternating-current systems in accordance with C22.1 Rule 10-400 (2).
●FEATURES
■Green LEDs indicate presence of voltage to ground for each phase of a power system.
▲ A ground fault (or phase loss) is indicated when a set of LEDs is off.
▲ For systems up to 240 Vac, LEDs are on when phase-to-ground voltage exceeds 25 Vac.
▲ For systems above 240 Vac up to 600 Vac, LEDs are on when phase-to-ground voltage exceeds 40 Vac.
▲ Redundant LEDs are used for reliability.
■ Pressing LAMP TEST causes all LEDs to light.
■Direct connection for voltages up to 600 Vac line to line.
▲Potential transformers (PTs) are required for voltages greater than 600 Vac.
■Provides faulted-phase indication for resistance-grounded systems and ungrounded systems.
