Earth Fault Relay Dealers in Bangalore

Features Software based design Instantaneous / Definite time Wide range of battery voltage Solid state reliability Principle of Operation: The relay measures the leakage current between battery and earth if the current increased more than the set value the relay trips as per time delay setting . The relay output contacts are hand reset type. Relay operation without any fault current is determined by trip test facility.

Prok dv's make Digital microprocessor/microcontroller based Earth Leakage Relays (ELR) withCore Balance Current Transformer (CBCT / ZCT) are used to detect leakage currents inelectrical power systems. ELR transmits a signal to activate the trip coil of theMCCB/ACB/OCB/CONTACTOR in the event of earth leakage resulting in automatic isolationof the load. ELR have been widely used and accepted because of field adaptability andare economic.Prok dv's make Earth Leakage Relay (ELR) MPEL series uses the state-of-the-art, Digitalmicroprocessor/micro controller based protection device to detect low level leakage dueto degradation of insulation of phase conductors or high impedance faults.The main featureof Digital microprocessor/microcontroller Earth Leakage Relay (ELR) continuous display ofearth leakage currents of the power system. The unit has immunity to external disturbancelike harmonics and transients. Specification Frame leakage protection for LT control panels and switch boards. 8 character 2 line LCD displays with back-lit. Test & Reset facility. CBCT / ZCT connection monitoring facility. Trip Circuit Failure indication. Immune to harmonics and transients. Tropicalized and rugged design.

Earth Fault Relay is sensed by measuring the neutral current. Normally in three phase system the vector sum of three phase current are zero hence no current flows from neutral to earth. If ground fault occurs the vector sum is not zero. If we can sense the current from neutral to earth we will get the residual current which we can say as earth fault current. Sensing this current calibrated we can compare with the set point to detect the earth fault.
