Protection relays detect abnormal operating conditions in an industrial system and may trigger an alert or isolate the offending device from the system. Common detection functions include; Arc-flash, temperature monitoring, ground fault, over-current, over-voltage, reverse power flow, over-frequency, under-frequency and phase loss, sequence or imbalance.
