Co-ordination of protective relays for 16MW load system using ETAP

This paper put forward an idea of Simulation of Co-Ordination of Protective Relays when they are subjected to distribution system for industry having load of 16 MW system in Electrical Transient Analyzer Program(ETAP) Software, by properly installing their time settings so that fault affected area should only isolated from healthy area, and if Primary protection of faulty area is not working than it's Backup Protection should become Active, in this paper 5 level(Stage) of Co-Ordination is done based upon fault current magnitude and it is observed that system is working properly.
