... PGR-4700 Sensitive Ground-Fault Relay 1. GENERAL The PGR-4700 is a ground-fault relay for ac power supply systems that require ground-fault detection as low suited for sensitive ground-fault protection on systems with significant harmonic content. Its output relays can operate in the fail-safe or non-fail-safe mode for undervoltage or shunt-trip applications ...
