[0002] Transmission and transformation is the transmission of electricity from power plants to power grids. It is the process of increasing low voltage and transmitting it over long distances. For the same power, the higher the voltage, the smaller the current. The smaller the current, the smaller the loss on the line. The transmission of current often leads to loss due to line heating, so during transmission, the voltage is increased through transformation to reduce the current and reduce heat loss. High voltage electricity is very dangerous, and the target electrical appliances do not need such high voltage, which requires reducing the voltage through transformation. Since multiple transformations are required in the process of current transmission, the transmission of current is called transmission and transformation.
