Electrical Elcb Diagram. For proper operation of elcb its need to bury a metallic rod deep in the soil and elcb is connected between the wire coming from the rod to the wire attached to the external metallic body of the electrical device or you can say that elcb is connected to the earth wire. The output other secondary winding of current transformer is connected to the relay circuit the relay circuit is connected to the circuit breaker.
An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock. Means it detects the earth leakage current and. Elcb and rccb both are the electrical protective device but their working principle and function are different.
If any current leaks from any electrical installation there must be any insulation failure in the electrical circuit it must be properly detected and prevented otherwise there may be a high chance of electrical shock if anyone touches the installation an earth leakage circuit breaker does it efficiently.
Here we will learn 2 designs first using transistors only and the second using ic lm324. Elcb consists of a small current transformer surrounding live phase wire and neutral wire. Elcb and rccb both are the electrical protective device but their working principle and function are different.
