METHOD FOR CHANGING THE ACTIVE NUMBER OF TURNS OF A CONTROL WINDING IN AN ELECTRIC SYSTEM, AND ELECTRIC SYSTEM COMPRISING A CONTROL WINDING

The invention relates to a method for changing the active number of turns of a control winding (12) in an electric system (10). The control winding is coupled to an AC voltage network for a specifiedperiod duration T, is designed for a specified nominal current strength IN, and comprises a first and a second tap (121, 122). The control winding is switched from a first continuous current state, inwhich a load current flows from the first tap to a load discharge line (15) via a first main path and the second tap is separated from the load discharge line, to a second continuous current state, in which the load current flows from the second tap to the load discharge line via a second main path and the first tap is separated from the load discharge line, according to a specified switch sequence plan. The switch sequence plan specifies that starting from the first continuous current state, the first tap is connected or remains connected to the load discharge line via a first transition path, and the first main path
