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.

Abstract: The present disclosure relates to a corona shielding material. The teachings thereof may be embodied in a material with an adjustable resistance and/or a corona shielding system which comprises an overhang corona shielding system (OCS). In some embodiments, a corona shielding material may include: a matrix; and a filler comprising doped and undoped particles in a given size fraction. A resistance of the corona shielding material is set by a concentration of doped particles in the filler particle size fraction.

Abstract: A stator of an electric machine includes a laminated core having slots for receiving windings of a multiphase winding system. The windings have winding ends, which are encased with an insulator across a partial length. In order to encase the winding ends with the insulator, a strand of a thermoplastic material is extruded onto the winding ends via a nozzle. During extrusion, the nozzle is moved relative to the winding end along the longitudinal extent thereof and an oscillating movement of the nozzle transversely to the longitudinal extent of the winding end overlays the movement along the longitudinal extent. As a result the thermoplastic material lies on the winding end and around the respective winding end in the form of loops.

Abstract: In a method for encapsulating a winding overhang of a stator which includes a laminated core with windings inserted in grooves of the laminated core such that winding ends protrude from the grooves to form a winding overhang at a distance from a laminated core end and run in a region between the laminated core end and the winding overhang so as to form intermediate spaces between the winding ends, at least one of the intermediate spaces is spanned by a polymer layer such as to prevent a flow of encapsulating compound through the at least one spanned intermediate space, and the winding overhang is encapsulated with the encapsulating compound after placing the stator in a housing of an electric machine.

Abstract: Various embodiments include an electrical insulation system for an electric motor comprising: a laminated core having slots and wire windings; an electrical surface 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: A surface coating for lightning protection is embodied as a composite material including a matrix formed from a polysilazane or of a polysiloxane, and filled with lamellar, ceramic particles having an electrically conductive coating of metal oxide. The surface coating may be applied to a blade of a wind turbine by applying the conductive coating in liquid form to the blade, allowing the surface coating to harden at room temperature, and pyrolyzing the surface coating via short periods at temperatures up to 700° C. to form a glassy, electrically conductive coating that is resistant to temperature changes.

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.
