AN INDUCTION DEVICE

摘要

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