Earth Fault Relay Testing System
Description & Specification
Earth Fault Relay Testing System is designed to provide exposure of protection device used to prevent faults in electrical circuits due to earth leakage current. The protection of electrical system is required to maintain any device in operation without failure.
There are various types of protective devices used in Power Systems. The knowledge of protective devices helps to use them smartly and avoid system breakdown. Earth leakage current gives rise to heat generation and progressive failure of insulation which leads to earth faults & sparks.
The Earth Fault Relay detects the leakage current well before they cross threshold limit. Provides complete learning platform related with the connection of Earth Fault Relay in transmission line and testing of Earth Fault Relay After experimenting with the students will be able to use Earth Fault Relay in Power Systems
