The power transformer and reactor has one or more windings which include one or more current carrying conductors. Around each conductor (4) is a first layer (6) with semiconducting properties, and around the first layer is a solid insulating part (7). Around the insulating part is a second layer (8) with semiconducting properties. The first layer is at the same potential as the conductor. The second layer essentially constitutes an equipotential surface surrounding the conductor(s). The second layer is connected to earth potential. |
