Abstract
In a method for cleaning an on-load tap changer () in a regulating transformer (), provision is made for the on-load tap changer () to comprise a moving contact () and a fixed contact (); for a cleaning signal to be generated; for the moving contact () to be frictionally moved relative to the fixed contact () on the basis of the cleaning signal. An on-load tap changer () in a regulating transformer () comprises: —a moving contact () and a fixed contact (); —a contact drive () which is coupled to the moving contact (); —a control device () which is connected to the contact drive () and is designed in such a manner that the control device can generate a cleaning signal and can transmit said signal to the contact drive (); wherein the contact drive () is designed in such a manner that the contact drive can frictionally move the moving contact () relative to the fixed contact () on the basis of the cleaning signal.
