Abstract: Various embodiments include an electrical insulation system for an electric motor comprising: a laminated core having slots and wire windings; an surface electrical insulation in the slots surrounding individual wires with a potting compound; and an absorbent material between the individual wires and within the wire winding bounded by surface insulation material. The absorbent material took up liquid impregnation resin during the manufacturing process. The liquid impregnation resin has cured and now forms the potting compound.

Abstract: Various embodiments include a passive component comprising: a substrate; and two conductor tracks disposed on the substrate. The substrate forms an electrically insulating bridge between at least two phases of an electrically rotating machine. Each of the two conductor tracks is coupled to a separate phase of the at least two phases so an electrical potential across the electrically insulating bridge is the same as in the insulation system of the machine and the potential load on the passive component corresponds to the potential load on the insulation system.

Abstract: A verification device for verifying an electrical overvoltage between two electrical conductors includes a conductor-track carrier made of an electrically insulating carrier material, a plurality of conductor tracks applied in spaced-apart relation from one another on the conductor-track carrier, and a measuring device acquiring an electrical resistance of one of the conductor tracks. Each of the two electrical conductors is electrically connected to at least one of the conductor tracks with the proviso that none of the conductor tracks is electrically connected to both of the two electrical conductors. The conductor tracks are configured such that a prespecified overvoltage between the two electrical conductors causes a partial discharge that changes the electrical resistance of the one conductor track between the one conductor track and another one of the conductor tracks that is electrically connected to one of the two electrical conductors.
