Electric Power Transmission and Distribution

Electric power transmission is merely the bulk transfer of electrical energy, from generating power plants to electrical substations located near demand centres. This is well defined from the local wiring between high-voltage substations and customers, which is typically mention to as electric power distribution. Transmission lines, when interconnected with each other, become transmission networks. The consolidate transmission and distribution network is known as the "power grid" in North America. Within UK, "power grid" is also known as the "National Grid”. A wide area synchronous grid, called an "interconnection" in North America, sprightly connects a large number of generators distributing AC power with the same corresponding frequency, to a large number of consumers.


Transmission lines are combinations of wires, called conductors that carry electric power from generating plants to the substations that gives power to customers. At a generating plant, electric power is “stepped up” to several thousand volts by a transformer and supplied to the transmission line. At numerous substations on the transmission system, transformers step down the power to a lower voltage region and deliver it to distribution lines. Distribution lines carry power to farms, homes, industry and businesses. The type of transmission structures used for any project is determined by the characteristics of the transmission line’s branches, including terrain and existing infrastructure.
