Dc Earth Leakage Relay Schneider

El731 is an ac dc sensitive earth leakage relay that offers complete coverage for all frequencies with values between 0 and 6.

Dc earth leakage relay schneider.

The relays can be used in the following ways. If an earth fault is present the fast response sensor detects the difference between the two currents and. The signals from the sensors are processed by the detector unit and leakage is detected. Find your earth leakage protection relay easily amongst the 111 products from the leading brands littelfuse schneider circutor on directindustry the industry specialist for your professional purchases.

Find out all of the information about the schneider electric electrical distribution product. February 19 2019 hilman rojak leave a comment on dc earth leakage relay schneider. 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. The two conductors wires or small bus bars are passed through a sensor.

Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage. 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. Dc earth leakage relay schneider. 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 earth leakage relay includes on board through label healthy and failure leds one per pole and includes a double pole volt free relay rated at 3a 230vac or 30vdc. The dc earth leakage relay detects leakages from dc power systems by measuring differential current between the ve and ve current carrying conductors. 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 dc leakage current is measured by electronic ag sensor inserted in each monitored load circuit.

The dc earth leakage relay is designed to monitor unearthed dc it systems for insulation deterioration or faults. Contact a supplier or the parent company directly to get a quote or to find out a price or your closest point of sale. 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.
