Description

Earth leakage Current give rise to generation of heat and result in progressive failure of insulation ,which leads to earth faults ,sparking flashovers, deterioration of earthling and finally results in catastrophic which destroys costly equipment’s, gadgets and precious lives. It is therefore essential to detect earth leakage current well before they cross the threshold limits and isolate circuit in the event of leakage.
