Earth Leakage Relay (Digital)

DELAB Earth Leakage Relay TM-18c is a micro-processor based electronic protection device designed to recognize low-level leakage or unbalanced current due to insulation loss on conductors or faulty equipment installed in the network.

It incorporates a real time continuous display of the earth leakage current value in true RMS ampere and allows the isolation of the faulty network or equipment if necessary.

A ring-type zero phase current transformer is used to detect and provide the continuous measurement of the leakage current.
