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.

Abstract: Method and device for monitoring the status of a sheath voltage arrester of a cable system, a verification signal being supplied to a measuring loop which comprises the sheath voltage arrester and a measurement signal which is subsequently produced in accordance with the frequency-dependent impedance of the sheath voltage arrester being measured at the measuring loop in order to establish the status of the sheath voltage arrester by evaluating the measurement signal.

Abstract: The present invention relates to a method for determining partial discharges at an electrical component (10). In the case of the method, an electrical signal that comprises partial discharge pulses due to the partial discharges at the electrical component (10) is detected. Through filtering of the electrical signal by means of n filters (18-20) having n differing filter characteristics, n filtered partial discharge signals are generated. Respectively one of the filtered partial discharge signals is assigned, respectively, to one of the n filters (18-20), n being greater than or equal to two. Finally, the partial discharges are determined by linking the n filtered partial discharge signals.
