Protection Relays & Controls Generator & Single-Function ProtectionGround Fault PGR-4300 SERIES (GFA300) Generator Ground-Fault Relay Description The PGR-4300 Generator Ground-Fault Relay provides a simple method for detecting a ground-fault condition on generators without the need for current transformers (CTs). This greatly simplifies the installation. In addition, it is compatible with both three- and four-pole transfer switches. This relay also monitors the neutral-to-ground path for continuity. The PGR-4300 is ideal for any generator or application where there is not sufficient space to install CTs. Features & Benefits FEATURES BENEFITS No CTs required Saves space and simplifies installation Adjustable pickup Adjustable trip setting provides a wide range of (100 - 1200 A) protection and allows system coordination Adjustable time delay Adjustable trip delay allows quick protection and Simplified Circuit Diagram (0 - 1.0 s) system coordination Form C ground-fault output contacts for alarming Output contacts or tripping purposes Analog output Provides means for connecting to an optional (0 - 1 mA) meter (PGA-0500) or control system G Monitors neutral-to-ground integrity and alarms if N-G continuity alarm ground path becomes open circuit Passive filtering Eliminates nuisance tripping Accessories PGR-4300 Control (Generator PGA-0500 Analog % Current Meter Ground-Fault Relay) Power Optional panel-mounted analog meter displays ground-fault current as a percentage of the set-point.
