Earth Leakage Relay Working Principle Pdf

An voltage elcbs were first introduced about sixty years ago and current elcb was first introduced about forty years ago.

Earth leakage relay working principle pdf. The working principle of voltage elcb is quite simple. Manufactures the most trusted dependable earth leakage relays for more than 15 years and they are time tested h series earth leakage are different from other normal leakage relays. Normally earth fault relay earth leakage circuit breaker and ground fault circuit interrupter etc. Are used to restrict the fault current.

One terminal of the relay coil is connected to the metal body of the equipment to be protected against earth leakage and other terminal is connected to the earth directly. Current earth leakage current earth leakage circuit breaker current elcb. It detects small stray voltages on the metal enclosures of electrical equipment. 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.
