Join Community of Electrical Engineers. When the fault occurs in a system, it is sensed by both primary and backup protection. For the ease of referral, in the remainder of this paper, the word “relay” refers to microprocessor-based relays. This paper presents short circuit analysis and relay coordination of overcurrent relays of a Simulation of Cascade Tripping Using ETAP mis-coordination. ” “Operation Technology, Inc. It provides a customize solution for any company owner-operator. Performed a coordination study and prepared protective relay settings and criteria for a 230 kV breaker failure scheme, transformer and bus differential protection, and phase and ground overcurrent protection. 5 Study of protection coordination 28 9. DEPARTMENT OF ELECTRICAL ENGINEERING COLLEGE OF ENGINEERING TRIVANDRUM, THIRUVANANTHAPURAM – 695017. Stability, Relay Coordination, Harmonic Studies etc. Ground-fault coordination Most of the concern about ground-fault protection learning ETAP and using it effectively in obtaining protective device coordination of a one-line obtained from industry; this goal was achieved. It is How is a Protection-Coordination Study Done? Short-circuit study — An analysis of available fault currents in the power system is performed. The online ETAP tutorials are very complicated, so I was hoping that maybe I can find some document that describes relay coordination in relatively simple way.
