The present invention relates to a tap changer which comprises multiple socket parts connecting multiple taps in parallel, which are arranged in each transformer; and a switch part which is formed at the end part of the socket parts and connecting each socket part to turn on and off. The tap changer, through the socket parts connecting the taps in parallel, controls the transformation ratio of multiple transformers at a time. Moreover, an operator does not carry out the tap changing directly, but carries out the electronic tap changing by a relay. |
