  • Set of high-voltage cables and method for producing a set of high-voltage cables
    Patent number: 10476251
    Abstract: A high-voltage device for receiving a high-voltage cable having a conductor designed to conduct an electrical current and a cable insulation surrounding the conductor, includes an insulation and a waveguide. The insulation includes an at least partly transparent or translucent field control unit from a siloxane polymer which is designed to at least partly surround the cable insulation of the high-voltage cable, the siloxane polymer including, in at least one portion of the field control unit, covalently bonded fluorophores and/or dielectric pigments. The waveguide is arranged such that a light signal caused by a partial discharge in the field control unit can be coupled from the field control unit into the waveguide.

  • Field Control Element For A High-Voltage Cable Accessory And Method of Optically Measuring Partial Discharges
    Publication number: 20180106852
    Abstract: A field control element for a high-voltage cable accessory comprises an electrically insulating material. The electrically insulating material includes a fluorescent dye adapted to convert a first radiation having a first wavelength and generated by an electrical discharge into a second radiation having a second wavelength longer than the first wavelength.
