The power transmission and transformation is that a power plant transmits power to a power grid, and the power plant increases low voltage (such as 50 kilovolts) to be far away from the power transmission, and the higher the same power voltage, the smaller the current, and the smaller the current and the smaller the loss on the line. The transmission of current often causes loss due to line heating, so that the voltage is increased through power transformation during the transmission, and the current is reduced so as to reduce heating loss. High voltage power has a high risk and the target appliance does not need such high voltage, which requires voltage reduction by power transformation. Since multiple power changes are required in the current transmission process, the current transmission is called power transmission and transformation.
