If an earth fault is present the fast response sensor detects the difference between the two currents and. 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.

Vigirex relays measure the earth leakage current in an electrical installation via their associated sensors. The two conductors wires or small bus bars are passed through a sensor. The measuring method is based on the principle that the positive and the negative current in a fault free load circuit sum to zero. Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage.

Dc earth leakage relay schneider. 20183 by schneider electric or repair at radwell a9d10806 ic60h earth leakage circuit breaker 1p n circuit breakers electric schneider schneider earth leakage protector ram lachman enterprises schneider rh99p earth. El731 is an ac dc sensitive earth leakage relay that offers complete coverage for all frequencies with values between 0 and 6. The dc leakage current is measured by electronic ag sensor inserted in each monitored load circuit.

The signals from the sensors are processed by the detector unit and leakage is detected. Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage. The relays can be used in the following ways. The ddea that is power supplied from the system to be monitored is connected to earth through an active current limited circuitry trying to keep the earth voltage at half the system voltage.
