Protection Relays and Controls GROUND-FAULT PROTECTION UNGROUNDED AC SYSTEMS PGR-3100 Series Ground-Fault Indication System Description The PGR-3100 indicates the presence of voltage on each phase of a three-phase system. The LEDs on the panel illuminate when voltage is present. When a ground-fault occurs, the voltage on the faulted phase reduces to ground potential, causing the LEDs for the faulted phase to dim and the LEDs for the unfaulted phases to become brighter. Ungrounded ac systems are required by the National Electrical Code (NEC) Article 250.21(B) and the Canadian Electrical Code Part 1, Section 10-106 (2) to have ground detectors, such as the PGR-3100, installed on the system. External potential transformers (PTs) can be used to step down system voltage, allowing the PGR-3100 to be applied Simplified Circuit Diagram to any system voltage. PTs are not required for system voltages up to 600 V ac.
