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.

A reinforcement element, comprises at least one sensor fiber adapted for strain measurements based on stimulated Brillouin scattering within said sensor fiber. Furthermore, a system for monitoring strain within a structure comprises a reinforcement element comprising at least one sensor fiber adapted for strain measurements based on stimulated Brillouin scattering within said sensor fiber, a pump laser for coupling in laser radiation of a pump frequency into said at least one sensor fiber, a Stokes laser for coupling in laser radiation of a Stokes laser radiation into said at least one sensor fiber, wherein the pump frequency and the Stokes frequency are different from one another and wherein the frequency difference between the pump and Stokes frequencies is within the range of acoustical phonons within said sensor fiber, a sensor adapted to obtain a stimulated Brillouin backscattering signal, and a network analyzer adapted for determining the complex transfer function of the sensor fiber to determine a spatially resolved strain measurement.
