DC Earth Leakage Relays

DC Earth Leakage Relays offered by us works on the principle of sensing the leakage current through Resistor Bridge. It senses the DC Earth leakage current for any equipment like switch boards, rectifiers, and battery chargers by sensing resistance between Positive-Negative terminals of DC system & earth. The lower resistance results in the loss of life or damage to equipment.

Technical Data

The relay senses the DC Earth leakage current for any equipments like Switch boards, Rectifiers, Battery Chargers by sensing Resistance between Positive- Negative Terminals of DC System & earth. Thus leakage current if any will be dependent on the resistance value between respective terminals, Higher the resistance , lower is the leakage current & vice versa. Lower resistance results in to loss of life or damage to equipment. PROTIME's Earth leakage relay senses leakage current through Resistor Bridge & energizes relay when Resistance
