About Electrical Earth Leakage Relay

Principle of operation

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. It also has an inbuilt CBCT open/breakage protection wherein the relay will trip on CBCT connection being open.

Under healthy conditions OK LED will glow. In case of CBCT secondary is open CBCT OPEN LED will glow and after set time delay the relay will trip and CBCT OPEN FAULT TRIP LED will glow. In case of Fault/Leakage the FAULT LED will glow and after set time delay the relay will Trip and FAULT TRIP LED will glow.

Q: What are the key benefits of using this earth leakage relay in electrical systems?

A: This relay provides reliable earth fault protection, minimizes electrical hazards, and ensures uninterrupted operation through rapid fault isolation. Its robust insulation resistance and mechanical life offer long-term durability.

Q: When should an earth leakage relay be installed in an electrical network?

A: It should be installed during the setup of new electrical systems or when upgrading existing circuits, especially in environments where earth leakage risks might compromise safety, such as residential complexes, industrial plants, or commercial buildings.

Q: Where is this earth leakage relay most suitable for application?

A: The relay is ideal for modular panels in residential, commercial, and industrial settings, ensuring safety and compliance in power distribution networks.

Q: What is the process for installing and commissioning this earth leakage relay?

A: Install the relay on a standard modular panel using the provided terminals for line (L) and neutral (N). After ensuring correct wiring, power the system, set the necessary parameters, and test for correct operation according to the manufacturers instructions.

Q: How does the relays build contribute to its durability and performance?

A: Built with a silver alloy contact, high insulation resistance (>100M), and a dielectric strength of 2kV, the relay ensures secure operation and longevity even in demanding conditions, capable of exceeding 100,000 mechanical operations.
