WebEarth leakage is when the current flowing in a system finds an alternative return path other than active and neutral conductors. The term “earth leakage” is associated with a residual current of small magnitude and is generally measured in the order of milli ampere (mA). Residual currents of higher magnitudes, measured in % of rated load ...
WebThe earth leakage relay is an electronic device that detects earth failures. The relay uses a toroid to measure the earth leakage current. A definite time operating characteristic of the earth leakage relay is provided with adjustable trip sensitivity and time delay. When a fault occurs, the relay’s trip function is activated.
