Earth leakage circuit breaker working.

An earth leakage circuit breaker elcb is a safety device used to directly detect the leakage current to the earth from an installation and cut the power supply. Basically elcb is used where the earth impedance is high. Means it detects the earth leakage current and. 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.

It detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. Earth leakage circuit breaker or elcb. Generally the current sensing devices termed as rccb and voltage detecting devices named as earth leakage circuit breaker elcb. An earth leakage circuit breaker elcb is a safety device used in electrical installations with high earth impedance to prevent shock.

Current earth leakage current earth leakage circuit breaker current elcb. Because of high earth impedance the voltage difference between the metallic part of the installation and earth. For many years the voltage operated elcb and the differential current operated elcb were both referred to as elcbs because it was a simpler name to.
