Patent number: 8198967Abstract: 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.Type: GrantFiled: June 3, 2011Date of Patent: June 12, 2012Assignee: ABB Technology AGInventors: Anders Bo Eriksson, Julia Forslin, Jan Anger, Jan Hajek

Patent number: 8183972Abstract: An oil filled high power transformer for high voltages with coils. The transformer including a number of stacked layers of, in the main concentric, insulated conductors forming transformer coils. The winding layers are separated by spacers. One or more spacers are provided with at least one integrated electrical discharge barrier extending off the central body of the spacer in the vicinity of the area where the spacer is in contact with a winding. Breakdown along spacer and alongside the spacer-oil interface is reduced getting improved breakdown strength of the oil filled transformer.Type: GrantFiled: September 29, 2006Date of Patent: May 22, 2012Assignee: ABB Technology Ltd.Inventors: Arne Hjortsberg, Jan Hajek
