Abstract

A method changes a transformation ratio, an impedance, or a voltage used for excitation of an item of electrical equipment. The item of electrical equipment includes: a tap winding having winding taps and a partial winding; and a tap changer that changes the transformation ratio, impedance, or voltage used for excitation. The tap changer has a first module that connects the winding taps to one another; and a second module with semiconductor switching elements for the switching-in, switching-out or bypassing of the partial winding. The method includes: receiving a request to change the transformation ratio, the impedance, or the voltage; checking a relevant parameter; and changing the transformation ratio, the impedance, or the voltage either by way of the first module or by way of the second module depending on the check of the at least one relevant parameter.
