Key Features of Earth Leakage Relay
- This relay operates on the core balance principle wherein the currents in the three phase of the system are summed by a core balance C.T. which for normal conditions equates to zero.
- In case of a leakage current to earth this balance is disturbed causing the electronic circuit to operate a relay within the unit.
- In this event the relay that is generally connected to circuit breaker operates thus tripping the main circuit.
- The electro mechanical relay operates on fault.
The Earth Leakage Relay is provided with a TEST push button for checking its operation and a reset button to reset the relay on operation.
- This helps in checking the proper functioning of the relay.
