EARTH FAULT RELAY TESTING SYSTEM

Product Code : SSID:ELE:104

EARTH FAULT REALY TESTING SYSTEM

is designed to provide ex-posure of protection device used to preventfaults in electrical circuits due to earth leakage cur-rent. The protection of electrical system is re-quired to maintainany device in operation without failure. There are various types of protective devices used in Power Systems. Theknowledge of protective devices helps to use them smartly and avoid system breakdown. Earth leakage currentgives rise to heat genera-tion and progressive failure of insulation which leads to earth faults & sparks. The EarthFault Relay detects the leakage current well before they cross threshold limit.This provides complete learning platform related with the connection of Earth Fault Relay in trans-missionline and testing of Earth Fault Relay. After experi-menting with the students will be able to use Earth Fault Relay in Power Sys-tems.

Features
