Abstract: A spacer tape is provided for spacing apart turns of a winding, which comprises a tape having an upper surface, a lower surface and a longitudinal axis, wherein the lower surface is adhesable and configured to be adhered to a conductor forming a turn of the winding, and spacers with an upper surface and a lower surface arranged on the tape, wherein the lower surface of the spacers is adhered to the upper surface of the tape, and wherein the upper surface of the spacers are adhesable and configured to be adhered to the conductor forming an adjacent turn of the winding.

Abstract: A gapped core leg for a shunt reactor, comprising magnetic core elements separated by spacers cast directly between the core elements. Accordingly, a rigid core leg construction is achieved.

Abstract: An induction device to be used in association with a high voltage electric transmission systems having at least one winding, at least one core frame, and at least one magnetic core leg arranged in the core frame. The core frame includes a plurality of core gaps including a plurality of spacers, and a plurality of core segments of a magnetic material. The core segments are being separated by at least one of the core gaps, and the winding is causing electromagnetic attraction forces to act in the core gaps. The induction device further includes at least one piezoelectric element arranged in one of the core gaps, and a control unit connected to the piezoelectric element. The control unit is arranged to provide an electrical signal for inducing vibrations of the piezoelectric element which counteract the electromagnetic attraction forces acting in the core gaps.

Abstract: An induction device for association with high voltage electric transmission systems having at least one core frame and at least one winding arranged around said core frame. The induction device has at least one magnetic core leg arranged in said core frame. The core frame includes a stack of core segments of a magnetic material being cooled by cooling medium, arranged in compression in the core frame, core gaps being arranged to separate the core segments, and a plurality of spacers, arranged in the core gaps between the core segments, with a cross section of hexagonal shape, having an upper and a lower end-face being in contact with the core segments. The spacers in at least one of the core gaps are arranged densely packed so as to form a compact filling in the core gap.
