Electrical Earth fault and Voltage variation indication device (up to 600 Amp load)

This Earth fault and Voltage variation indication device will give the Hooter noise lamp indication at the time of Earth fault and Voltage variation, so the necessary action can be taken.

Features of Device

  • Electric Shock can be avoided due to Earth fault.
  • Electric Fire can be avoided due to Earth leakage current.
  • Earth leakage current can be controlled so Electricity bill amount will not increase due to Earth leakage current.
  • Damages of components can be avoided due to voltage variation.

This device has a facility to set Earth leakage current so depending upon the load situation, Earth leakage current setting can be done.
This device does not have any breakdown supply problem.

Specification

Wall mounted device consists of Control MCB, Earth leakage relay with earth leakage current indication, Fault Hooter noise indication lamp, Push button for Hooter reset, Voltage protection relay, Voltmeter, Control Relay, and Loose current transformer.

  • Earth fault and Voltage variation indication device shall be mounted on wall.
  • Connect three phase neutral supply to control MCB.
  • Insert current transformer on Incoming four core cable.
  • Connect two wire of CT to S1 and S2 terminal of Earth leakage relay.

Overall Dimension of Panel 250(L)x 300(H)x 160(D) mm

Working of Fault Indication Device

Earth Fault Protection

  • At the time of Earth fault/Earth leakage there will be Earth fault Hooter noise lamp.
  • Press the Push button to stop the Hooter noise lamp.
  • The Hooter noise lamp will be off, If the Earth fault occur earlier.
  • The Hooter noise lamp will remain on, If the Earth fault exists.
  • Now locate the Earth fault so that the Hooter noise lamp shall be off.

Voltage Variation Protection

  • At the time of Voltage variation, there will be Hooter noise lamp.
  • Change position of Actuator switch to stop the Hooter noise lamp.
  • Check the Voltage on voltmeter and take necessary action.
  • After availability of Proper Voltage, there will be Hooter noise lamp, Now change position of Actuator switch to stop the Hooter noise lamp.
