PGR-3100 MANUAL GROUND-FAULT INDICATION SYSTEM
FEATURES:
•Green LED’s 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 LED’s is off.
■ LED’s are on when phase-to-ground voltage exceeds 30 Vac.
■ Redundant LED’s are used for reliability.
• Pressing LAMP TEST causes all LED’s to light.
• Direct connection for voltages up to 600 Vac line to line.
■ Potential transformers (PT’s) are required for voltages greater than 600 Vac.
• Provides faulted-phase indication for resistance-grounded systems and ungrounded systems.
The PGR-3100 is a self-powered ground-fault indication system. Presence of phase-to-ground voltage is indicated by redundant LED’s (two per phase). The respective phase LED’s are off when phase-to-ground voltage is less than 30 Vac. 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 CEC 10-106(2).
