WebA ground relay must detect all phase-to-ground faults within its defined zone of protection under conditions which produce minimum fault current. The ground relay zone of protection can be defined as a current threshold or measured impedance. The classical method for detecting ground faults on a looped system has been to use directional WebELR Wiring diagram . A typical wiring diagram of an earth leakage relay is shown below. Operational power is applied to the terminal A 1 and A 2 of the ELR and the CBCT is connected to the terminals T 1 and T 2.The normally closed terminals of the fault signalling contacts are connected to the Undervoltage release coil of the circuit breaker.
