    摘要: A power transformer having at least one high voltage winding and one low voltage winding. Each of the windings includes at least one current-carrying conductor, a first layer having semiconducting properties provided around said conductor, a solid insulating layer provided around said first layer, and a second layer having semiconducting properties provided around said insulating layer. The windings are intermixed such that turns of the high voltage winding are mixed with turns of the low voltage winding.

    摘要: A power or regulating transformer with voltage regulator includes regulating windings made of a flexible conductor having an electric field containing mechanism that forces the electric field due to the current in the winding to be contained within the flexible conductor. Since virtually no electric field is to be found outside the flexible conductor of the regulating winding, the regulating winding may be formed without having to consider the electric field distribution, thus providing for a transformer with a favorable regulating winding design.

    摘要: A high power static electromagnetic device with a flux path, a main winding and one or more regulation windings surrounding portions of the flux path. A control device is coupled to the flux path for selectively admitting the flux therein. In an exemplary embodiment, multiple flux paths are selectively turned on and off for including and excluding the regulation windings from the circuit. The windings may be formed of a magnetically permeable, field-confining insulating cable.

    摘要: A rotating asynchronous converter and a generator device having a first stator connected to a first AC network with a first frequency f1, and a second stator connected to a second AC network with a second frequency f2. The converter has a rotor which rotates in dependence of the first and second frequencies f1, f2. The stators each have at least one winding formed of at least one current-carrying conductor, and an insulation system, formed of semiconducting layers each forming an equipotential surface, and a solid insulation between the semiconducting layers.

    摘要: A high voltage power cable termination with a current lead, a power cable having a first tube and an outer conductor, e.g., a superconductor, whose electrically conducting properties improve at low temperatures, arranged around the first tube and intended in use to be cooled to low temperatures by cryogenic fluid flowing through the first tube, a joint for electrically connecting one end of the current lead to the conductor at one end of the cable at or adjacent to one of the first tube, and a second tube communicating with the first tube at or adjacent to the joint for conveying cryogenic fluid to or from the first tube. The first and the second tube are arranged so that, in use, no cryogenic fluid conveyed by the tubes contacts the conductor or the current lead at the joint. The invention also relates to electrical apparatus, e.g., a high voltage induction device, having such a termination.
