WebPhase and neutral conductors go through the CBCT to the load. Any leakage to the earth causes an imbalance between the phase and neutral currents. Earth fault relay senses this current and trips the circuit breaker. Earth leakage relays can be found in domestic distribution boards and are used to sense insulation failures and to prevent ... WebConsider earth fault is occurred in the load means the leakage current starts flow through a new path, from phase terminal to earth. This leakage current is called residual current. RCCB is specially designed to protect the …
