2. Overhead power line - Wikipedia

   en.wikipedia.org/wiki/Overhead_power_line

   Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.

3. Electric power transmission - Wikipedia

   en.wikipedia.org/wiki/Electric_power_transmission

   Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network .

4. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. [ 1 ]Primary ...

5. Transmission line - Wikipedia

   en.wikipedia.org/wiki/Transmission_line

   Transmission line. Schematic of a wave moving rightward down a lossless two-wire transmission line. Black dots represent electrons, and the arrows show the electric field. One of the most common types of transmission line, coaxial cable. In electrical engineering, a transmission line is a specialized cable or other structure designed to conduct ...

6. Electrical grid - Wikipedia

   en.wikipedia.org/wiki/Electrical_grid

   Electric power transmission is the bulk movement of electrical energy from a generating site, via a web of interconnected lines, to an electrical substation, from which is connected to the distribution system. This networked system of connections is distinct from the local wiring between high-voltage substations and customers.

7. North American power transmission grid - Wikipedia

   en.wikipedia.org/wiki/North_American_power...

   The electric power transmission grid of the contiguous United States consists of 120,000 miles (190,000 km) of lines operated by 500 companies. The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western ...
