Introduction to Residual Current Relay
A residual current relay (RCR), also known as a ground – fault relay, is an electrical device designed to monitor the residual current in an electrical circuit. In a normal situation, the sum of the currents in the live and neutral conductors of a balanced electrical circuit is zero. However, when there is an insulation fault, leakage currents may flow to the ground, and this imbalance is detected by the residual current relay. Once the detected residual current exceeds a pre – set threshold, the relay will operate and trigger a protective action, such as tripping a circuit breaker, to prevent electrical hazards like electric shock and fire caused by ground faults. Residual current relays are widely used in various electrical systems, including industrial, commercial, and residential applications. Residual Current Relay
