Prok dv'smake DIGITAL MICROPROCESSOR / MICROCONTROLLER BASED IDMT / DEFINITE TIME /INSTANTANEOUS EARTH FAULT RELAY (EFR) can be employed with various earth fault protectiveschemes, which are explained in brief with figures. (85-275V AC 50Hz) The display shows Prok Dvs REF – 1A or Prok Dvs REF – 5A (Factory set) Note: In-5A or In-1A shows the relay rated current. Most of the Industries, Commercial establishment and domestic application the earthing of electrical system is ignored and improper maintenance of the same. No. Prok dv’s brand earth leakage relay MPEL series uses the state of the art microcontroller based protection device to detect low level leakage due to degradation of insulation of phase conductors or high impedance faults. Buy Prok Dv's Earth Leakage Relays at Best Price with us. Protection for Mining & Control Engineering, Earth Leakage protection for Feeders / Motors / Generators / Transformers / Mobile, Protection for hazardous sensitive environments like Oil Refineries/ Cement Plant/Steel. Conventional over current and shortcircuit protection device are not designed detect earth leakage currents. No. 6th Block, Rajajinagar (KSSIDC) The LEDs are provided for indicating power ON statusand to indicate IDMT or DEFINITE TIME or INSTANTANEOUS mode operation. With the aid of modern machinery and technology, we have been able to manufacture, supply, export and trade Phase Failure Relay.Fully static, these relays are widely used for large number of motor applications as are developed in tandem with the guidelines laid in the industry. The moment the Earth Fault crosses the Threshold Set value, an trip command is given by the relay to the trip circuit with a time elapse.
