The new generation of electronic relays can take the place of many mechanical relays. One electronic relay can respond to a variety of fault conditions which may include: Instantaneous Overcurrent, Time Overcurrent, Differential Overcurrent, Ground Fault Overcurrent (Zero Sequence), Current Imbalance (Negative Sequence), Under/Over Voltage, Under/Over Frequency, Loss-of-Field, and Phase Distance to name a few.
