|
Residual current device |
Sensitive piece of equipment which can break a circuit at small current leakages (mA range) Ple: neutral and live wire contain same current Uses COMPARATOR to cut the current if there is an imbalance in Current between live and neutral wires. |
|
|
COELB |
Current operated earth leakage circuit breaker Breaks circuit when it detects small current leakages. Live and neutral wire wound around a transformer with same number of windings Third winding connecting to relay that is attached to a circuit breaker Difference b/w neutral and live wire➡️ induces current in the third winding➡️ circuit breakage |
