Description

The PGR-3100 indicates the presence of voltage on each

phase of a three-phase system. The LEDs in the panel light

up 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.

Applications

Ungrounded ac systems are required by the National

Electrical Code (NEC

detectors installed on the system. External potential

transformers (PTs) can be used to step down system

voltage, allowing the PGR-3100 to be applied to any system

voltage. Voltage inputs do not require PTs for system

voltages up to 240 Vac.
