February 19 2019 hilman rojak leave a comment on dc earth leakage relay schneider.
The measuring method is based on the principle that the positive and the negative current in a fault free load circuit sum to zero.
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.
Vigirex relays measure the earth leakage current in an electrical installation via their associated sensors.
Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage.

The dc earth leakage relay is designed to monitor unearthed dc it systems for insulation deterioration or faults.
Ground fault protection rh10 rh21 rh99 with manual reset earth leakage alarming same models plus rh99 with automatic reset ground fault protection.
Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage.
The signals from the sensors are processed by the detector unit and leakage is detected.
El731 is an ac dc sensitive earth leakage relay that offers complete coverage for all frequencies with values between 0 and 6.
If an earth fault is present the fast response sensor detects the difference between the two currents and.

The dc earth leakage relay is capable of detecting earth faults on charger rectifiers and transformer secondary as well as standard dc supplies from batteries or power supplies.
The dc leakage current is measured by electronic ag sensor inserted in each monitored load circuit.
The two conductors wires or small bus bars are passed through a sensor.
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.
