    摘要: A power transformer/inductor includes at least one winding. The winding is made of a high voltage cable that includes an electric conductor, and around the electric conductor is arranged a first semiconducting layer, around the first semiconducting layer is an insulating layer, and around the insulating layer is a second semiconducting layer. The second semiconducting layer is directly earthed at both ends of the winding and furthermore at least at two points per turn of every winding such that one or more points are indirectly earthed.

    摘要: The invention relates to a rotating electric machine comprising a stator (4) provided with windings drawn through slots in the stator, and a rotor (1) having a central axis (2) and poles (5, 6) in the form of pole pieces (8, 9) provided with windings and forming solenoids, pole gaps (13) being arranged between the poles. The machine also comprises coil supports (15, 16) in said pole gaps in order to support the solenoid windings (10, 11). It is characterized in that the coil supports (15, 16) are arranged in pairs and that each coil supports (15, 16) is shaped so that it supports only a part of the solenoid windings (10, 11) of the two adjacent poles (5, 6).

    摘要: A method and apparatus for location of partial discharges in an electric high-voltage apparatus, such as a power transformer, which is arranged in a container filled with an insulating medium is provided. At least three ultrasonic detectors are applied with mutually known positions on the outside of the container and in acoustic contact therewith. The times of arrival of a wavefront arriving at the detectors and originating from a partial discharge are determined, and on the basis of the times of arrival and on the basis of the known mutual positions of the detectors, the direction the partial discharge is determined.
