Abstract

An operational setting of an on-load tap changer used to switch between various winding taps of a tapped transformer is determined by first placing the on-load tap changer in operation with the tapped transformer and then moving the changer in a first rotational direction through a regulating range of its stationary operational settings on different winding taps of the tapped transformer toward an end abutment of the tapped transformer. The position is registered on reaching the end abutment of the regulating range of the on-load tap changer, and then the movement is reversed to return to the first stationary operational setting that is then configured as a predefined operational setting with the help of the parameterization that is stored in a nonvolatile memory of the control device.
