  • Electric insulation material, an electric device comprising the insulation material and a transformer
    Patent number: 8178780
    Abstract: An electric insulation material for an electric device includes one or several electrical conductors and an electric insulation material arranged around the conductor or between the conductors, which insulation material is impregnated with a dielectric insulation liquid. The electric insulation material includes a main layer that is provided with a surface layer that has a dielectric constant that is lower than the dielectric constant of the main layer.
    Type: Grant

  • Transformer with voltage regulating means
    Patent number: 6995646
    Abstract: 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.

  • DC TRANSFORMER/REACTOR
    Publication number: 20010019494
    Abstract: The present invention relates to a DC transformer/reactor comprising a magnetic circuit, wherein the magnetic circuit comprises a magnetic core and at least one winding. The winding comprises at least one current-carrying conductor. Each winding comprises also an insulation system, which comprises on the one hand at least two semiconducting layers, wherein each layer constitutes substantially an equipotential surface, and on the other hand between them is arranged a solid insulation.
