Background

The concept of power transmission and distribution includes three aspects, namely power transmission, power transformation and power distribution. The power transmission refers to the transmission of electric energy, and through power transmission, a power plant which is far away (can reach thousands of kilometers) is connected with a load center, so that the development and the utilization of the electric energy exceed the limit of regions; the transformation refers to the process of converting voltage from low level to high level (boosting) or converting high level to low level by using certain equipment, and the distribution is a distribution means for distributing power to users in an electric energy consumption area, and directly serves the users.

Both power transmission and distribution facilities include equipment such as substations and lines. All transmission equipment are connected to form a transmission network. The network of distribution equipment from the transmission grid to the users is called the distribution grid. They are sometimes also referred to as transmission and distribution systems. Transmission systems and distribution systems, together with power plants and consumers, are collectively referred to as power systems. The various electrical devices in the power system have their own voltage ratings which make up the voltage rating of the overall power system. The voltage used for power transmission is higher than the distribution voltage. The division of transmission and distribution voltage limits is not fixed and varies with the area covered by the grid and the size of the capacity.
