The function of tap changer for transformer
The tap changer of the power transformer is used to adjust the output voltage of the transformer. As the voltage in the power grid is not exactly the same, in order to make the transformer no matter what position in the grid can output rated voltage, the transformer in the high-voltage winding set a number of taps, and will be tapped into the tap switch, by opening about the grid connected. In this way, the switch can be connected with different transformer windings to change the turn ratio of high and low voltage windings, so as to adjust the output voltage of the transformer.
