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.
