1. The document summarizes the key components and functions of a 132KV Gomal University Grid station substation. It describes equipment like incoming transmission lines at 132KV, transformers to step down voltage, circuit breakers, switch gears, isolators, lighting arresters, capacitor banks, bus bars, cables, and insulators. 2. The substation contains a control room with auxiliary panels, relay panels, and control panels to monitor and protect the overall system. It also has a switch gear room and DC battery room. 3. Power enters the substation via high voltage transmission lines, is stepped down by transformers, then exits to distribution lines at lower voltages to deliver electricity to customers. The substation monitors
