    Abstract: The invention is related to a wound transformer core (10, 66, 82) with at least one core loop (12, 14) made of magnetic material, comprising multiple thin amorphous band-like iron sheets (16) which are concentrically stacked around at least one center axis (18, 20). A lower yoke section (24), an upper yoke section (22) and at least two limb sections (26, 28, 30) are developed, comprising a modular plate-like support structure (40, 74, 76) which is glued upright to the center axis (18, 20) on both face sides (70, 72) of the lower yoke section (24) and on both face sides (70, 72) of each limb section (26, 28, 30) in that way, that neighboured iron sheets are glued together at their outer edge. The modular plate-like support structure (40, 74, 76) comprises for each face side (70, 72) of the belonging core sections (24, 26, 28, 30) at least two plate-like modules (42, 44, 46, 48, 50, 86, 88, 90), which are connected each to each other by a first (100) or second (110) plug-in connection..

    Abstract: The invention is related to a voltage control system (10, 70) for medium voltage applications, comprising the following components: a booster- (12, 76) and a feeder-(18, 78) transformer with respective primary and secondary winding, wherein the secondary winding (22) of the feeder transformer (18, 78) is electrically connected with the primary winding (14) of the booster transformer (12, 76) in an intermediate circuit (50), wherein at least one of the transformer windings (14, 22) in the intermediate circuit (50) comprises at least two taps (24), wherefrom one is selectable as active tap, wherein electrically adjacent taps (24) are assigned to different groups (26, 28). The system is comprising further respective contactor switches (20, 32, 34, 36, 38, 40) which are associated to each of the taps (24) which are selectively switchable into the intermediate circuit (50) therewith, wherein not more than one contactor switch (20, 32, 34, 36, 38, 40) of a group (26, 28) is switchable at the same time, respective commutation resistors (42, 44) in electrical series connection with the taps (24) of each group (26, 28). The system is comprising further a common cabinet (56, 72) wherein the aforementioned components are arranged in and connection means (52, 54, 88) in order to connect the secondary winding (16) of the booster transformer (12, 76) with an electrical energy supply network in that way, that the secondary winding (16) of the booster transformer (12, 76) is in series with a transmission line that's voltage is to be controlled.
