Description

The PGR-3100 indicates the presence of voltage on each phase of a 3-ph 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. On A resistance grounded or ungrounded system the LEDs for the unfaulted phases 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 to a ny system voltage. PTs are not required for system voltages upto 600 VAC.
