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 fault relay schneider.

A din rail mounted current sensing relay dedicated for dc earth fault monitoring such as insulation deterioration on a dc system. The dc earth leakage relay is capable of detecting earth faults on charger rectifiers and transformer secondary as well as. Ground fault relays do not provide overcurrent or sh ort circuit protection. Ground censor ground fault protection system type gc keywords.

Our range encompasses voltage frequency relays earth leakage relays idmt relays diesel engine controllers protections current earth fault relays earth monitoring relays earth leakage monitors voltage stabilizers battery chargers rectifiers and other products. Dc power systems and stationary battery in switchgear and control applications are typically designed and operated as ungrounded systems which means that there is no intentional low resistance or solid connection to ground from either the positive polarity or negative polarity of the dc system. Thus leakage current if any will be dependent on the resistance value between respective terminals higher the resistance lower is the leakage. If there is no fault the voltage with respect to earth is equally di.

Dc earth leakage relay responding to a negative or positive earth fault will illuminate the appropriate led on the unit facia indicating precisely which pole is earthed. The internal relay trips to provide a warning signal. The se 601 is a microprocessor based ground fault monitor for ungrounded dc systems. A vigirex ground fault system includes these components.

What is dc ground fault. Se 601 manual spanish se 601 3d model. Littelfuse ground fault protection relays offer the needed protection against ground faults. The unit is supplied complete with a dedicated dc earth fault ct type fox21 ctd this allows the relay to have two switchable earth fault ranges of 1 20 ma and 10 200 ma.

To detect the earth fault first we need to check the values of positive and negative voltages with respect to earth using multimeter. This can be dangerous to nearby personnel and could result in equipment damage. Ground censor created date. Let us assume the system dc voltage is 120v.

Its output relay can operate in the fail safe or non fail safe mode for undervoltage or shunt trip applications.
