Operation
Sensing the resistance between positive- negative terminals &
earth, this equipment is used for sensing the DC earth leakage current
for electrical equipment such as L.T. Panels and Switch boards.
Leakage current always depends on the resistance value between
respective terminals, therefore, higher the resistance, lower is the
leakage current and vice versa. Our earth relay senses leakage current
through Resistor Bridge & energizes relay when Resistance value
goes out of the range selected on the dial thus assuring long life of
the equipment.
