Sub-Station The Electrical Sub-Station is the part of a power system in which the voltage is transformed from low to high or high to low for transmission,distribution,transformation and switching.The main components of an electrical Sub-Station are power transformer,circuit breaker,bus-bar,lighting arrester and insulator. Lighting Arrester It is used for the protection of the equipment at the sub-station against travelling waves.It is connected between the line and earth in parallel with the equipment to be protected at the sub-station. Single Line Diagram of sub-Station Working of Sub-Station Electricity has to be transmitted over large distances as the place where the power is being generated and the place where it is consumed can be far apart.The electricity is transmitted at very high voltages and low currents to reduce...
