In this paper, the authors describe the system characteristics during short circuit condition and will act as a path to design the protective scheme for the undertaken circuit. The most severe short circuit condition i.e. 3 phase to ground fault is tested on actual 72 bus system considering a 220 KV Masudpur substation as the test system. During this condition very high current flows through the system which damages the equipment. It also causes the interruption in the supply provided to the customers.
