Microprocessor Based Digital ELR 300mA-30A

The rise of leakage current in Electrical Power Distribution are quite dangerous , resulting in Electrical hazards and catastrophe. Leakage Current are due to deterioration of insulations, negligence of wire man, Bad wiring, Inferior / substandard usage of Electrical Materials , ageing or endurance of Electrical environment . First and foremost importance should be given for the proper earthing of electrical net work-system. Most of the Industries, Commercial establishment and domestic application the earthing of electrical system is ignored and improper maintenance of the same.

The Earth Leakage Current are very low and are sensitive leakage current can be detected by Earth Leakage Relay and core balance current transformer. ELR detects the Leakage Current in the circuit and isolate the power supply by switching off the tripping device (circuit breaker / contactor etc).
