Electrical power system consists of generation, transmission, and distribution systems. The grid station is a link between power generation and the area where power is distributed. Numerous equipments are available in grid stations i.e. isolators, circuit breakers, earth switches, lightning arresters, relays, capacitor banks, and power transformers. Grid Station of 132 KV is located at Larkana site Pakistan at a distance of 3 Kilometers from QUEST campus to supply electricity to the industrial, commercial, and residential consumers for utilization. Faults mainly occur on the power system which badly affects the performance of equipment and causes revenue loss. Very expensive equipments are available in grid stations, protection are necessary otherwise equipment may damage or fail due to flow of massive currents during a fault condition. Protection in grid station increases the reliability and revenue of the utility company. In a Larkana site grid station, different protective devices are used to protect the equipment against faults. The Power transformer is the essential component of grid stations which provides power to the consumers for utilization. In this study, the essential components of 132 KV Larkana grid station are discussed and performance of instantaneous over current relay is analyzed through MATLAB Simulink Software for the protection of the 11KV feeder.
