The invention relates to a regulating winding for a transformer in which a plurality of helical current-carrying conductor loops are connected in series with each other, whereas a plurality of non-current-carrying helical potential control loops are provided adjacent to the current-carrying loops and are connected to appropriate ones of the current-carrying loops in such a way that a substantial increase in the series capacity of the regulating winding is obtained with a relatively small increase in the space required for the regulating winding. |
