Transmission and Transformation Engineering Information _ Transmission and Transformation Tutorials bring together standard specifications and technical information related to transmission and transformation. The transmission of current often results in losses due to the heating of the line, so the voltage is increased through the transformation during transmission to allow the current to flow. Smaller to reduce heat loss. High voltage is very dangerous, and the target appliances do not need such a high voltage, which requires reducing the voltage by changing electricity. Since multiple power transformations are required in the process of current transmission, the transmission of current is called power transmission and transformation.
