Local Circuit Breaker Protection Relays and Controls Arc-Flash Monitoring PGR-8800 SERIES (D1000) Arc-Flash Relay Description The PGR-8800 is a microprocessor-based relay that limits arc-fault damage by detecting the light from an arc flash and rapidly tripping. Phase-current-transformer inputs are provided for current-constrained arc-flash protection and, when so equipped, a programmable definite-time overcurrent function can be enabled. An optical sensor on the PGR-8800 and adjustable trip level reduce the chance of nuisance tripping by setting a threshold for ambient light. Sensors, inputs, and connections are monitored to ensure fail-safe operation. A secondary solid-state trip circuit provides a redundant trip path. A USB port is used for configuration and access to event logs and graphs. Simplified Circuit Diagram 5-A-SECONDARY PHASE CTs (Recommended) Optical Sensors A D The PGR-8800 accepts both PGA-LS10 and PGA-LS20/ PGA-LS30 optical sensors, designed to collect light over a B wide angle and with high sensitivity. For fast fault location, front-panel and sensor LEDs indicate sensor health and C which sensor detected an arc fault.
