Electric transmission is the process of delivering the generated electricity - usually over long distances - to the distribution network located in populated areas. An important part of this process includes transformers that are used to increase voltage levels to make long distance transmission viable.

The system of electrical transmission lines combined with power plants, distribution systems and substations to form what is known as an electrical network. The electricity grid meets society's electricity needs and is what drives electricity from generation to end use. Since power plants are usually located outside densely populated areas, the transmission system must be quite large.

Power transmission lines, or transmission lines, carry electricity from one place to another. Typically, this electricity is an alternating current, so the elevating transformers can increase the voltage.

Overhead transmission lines are extremely high voltage, between 100 kV and 800 kV, and make up most of the long-distance transmission. They must be of high voltage to minimize energy losses to the resistance.
