Mining Applications
Continuous NGR monitoring detects resistor failure within seconds, reduces transient overvoltage risk, removes risk of ground fault detection failure
Ground fault detection main or backup protection to detect a ground fault anywhere on the monitored system
Adjustable pickup (0.5 to 4 A)- select greatest sensitivity without false operation
Adjustable time delay (0.1 to 2 s)- adjustable trip delay allows system coordination
Selectable fail safe or non-fail safe operating modes allows connection to shunt or undervoltage breaker coil or alarm system
Extended resistor trip time
