Dongguan 2016 Hengli electrician certificate agency review

From production to consumption, electric energy generally goes through four links: generation, transmission, distribution and consumption. Electricity is power energy that is easy to transport and access. The entire process of electricity production, transmission, distribution and use is actually realized at the same instant. This whole process is a whole closely linked by power plants, power supply bureaus (stations), substations, distribution transformers and users. It is the process of power transmission and distribution from power plants to power users.

Electric energy is produced by power plants. Due to the limitation of generator insulation conditions, the maximum voltage of the generator is generally <> and below. However, power plants and places where electricity loads are concentrated (also called load centers) are often tens, hundreds or even thousands of kilometers apart. In order to reduce the power loss of the lines and increase the distance of power transmission, the power generated by the power plant usually requires By increasing the voltage, power transmission systems of different voltage levels can be connected. Then it becomes a lower level through the substation
