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. Se 601 manual spanish se 601 3d model. If there is no fault the voltage with respect to earth is equally di. A vigirex ground fault system includes these components.

The se 601 is a microprocessor based ground fault monitor for ungrounded dc systems. Let us assume the system dc voltage is 120v. The internal relay trips to provide a warning signal. What is dc ground fault.

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 capable of detecting earth faults on charger rectifiers and transformer secondary as well as. A din rail mounted current sensing relay dedicated for dc earth fault monitoring such as insulation deterioration on a dc system. 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.

Littelfuse ground fault protection relays offer the needed protection against ground faults. Ground fault relays do not provide overcurrent or sh ort circuit protection. Its output relay can operate in the fail safe or non fail safe mode for undervoltage or shunt trip applications. Vigirex ground fault relay this has control powe r inputs inputs from the sensor outputs to the disconnect device and electronic circuitry that determines if the ground fault exceeds the trip level.

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. Ground faults occur when electricity travels an unintentional path between a power source and electrical ground. Ground censor created date. With 14 years of experience in the industry we are able to offer wide range of electrical and electronic products.
