FIELD: electrical engineering.
SUBSTANCE: in the method for performing a switching process in an on-load tap changer between winding taps of a tapped transformer, the switching process for an on-load tap changer is subdivided into a plurality of phases according to the reactor switching principle. In these phases, the switching contacts in use are monitored and are completely opened or closed by capacitors in the controller during the actuation and in the event of failure of the energy supply. Thereby critical switching states are prevented.
EFFECT: technical result is improved reliability.
