Description
The PGR-3200 continuously monitors the insulation integrity
of ungrounded electrical systems for ground faults. The relay
provides two warnings for predictive purposes and one alarm.
When the power system is de-energized, the relay monitors
the insulation for damage, providing predictive maintenance
and troubleshooting for developing ground faults.
When the power system is energized, the relay monitors
the system for ground faults and provides warnings as well
as an alarm.
Applications
The units operate on ungrounded systems up to 6 kV,
1-phase or 3-phase, 50 or 60 Hz. The relay can be directly
connected to power systems up to 1,300 V. Higher voltage
requires a pre-calibrated high tension coupler (PGH)
connected between the phase conductor and the relay.
Features/Benefits
• Meets National Electrical Code (NEC®) Article 250.21(B)
requirements for ungrounded systems
• Provides 2 warnings at different levels (30 kΩ and 50 kΩ)
and 1 alarm (10 kΩ)
• Analog output and optional meter (PGA-0510)
• DIN-rail or surface mount for ease of installation
