The document discusses the structure of a power system, including its key components and voltage levels. It defines an electric power supply system as the conveyance of electric power from a power station to a consumer's premises. The main components are the generating system, transmission system, and distribution system. Voltage levels vary between each section, with generating systems using 11KV or 33KV, transmission systems using higher voltages of 132KV, 220KV, 400KV and 765KV, and distribution systems using primary voltages of 33KV or 11KV and secondary voltages of 400V or 230V. A pictorial view of an AC power system is also presented.
