Abstract
A high-voltage device has an inner conductor and an insulating member that surrounds the inner conductor along the longitudinal direction thereof. In order to increase the reliability of the high-voltage device, at least one optical waveguide rests against the inner conductor in at least some sections, extends out of the insulating member and can be connected to an evaluation unit for recording measured temperature values. Furthermore a method measures a temperature of the inner conductor of the high-voltage device.

1-10. (canceled)
A high-voltage device, comprising:
- an inner conductor;
- an insulating member surrounding said inner conductor along a longitudinal direction thereof;
- and
- at least one optical waveguide which, at least in some sections, is guided on said inner conductor, is brought out of said insulating member and is connected to an evaluation unit for recording measured temperature values.
A high-voltage installation, comprising:
- a high-voltage device containing an inner conductor, an insulating member surrounding said inner conductor along a longitudinal direction thereof, an evaluation device, and at least one optical waveguide which, at least in some sections, is guided on said inner conductor, is brought out of said insulating member and is connected to said evaluation unit for recording measured temperature values;
- and
- at least one high-voltage component at a high-voltage potential being electrically isolated from a ground potential by means of said high-voltage device.
A method for measuring a temperature of an inner conductor of a high-voltage device, the inner conductor being enclosed by an insulating member in a longitudinal direction, which comprises the steps of:
- injecting a light signal into an optical waveguide which, at least in some sections, is guided on the inner conductor, is brought out of the insulating member and is connected to an evaluation unit for recording of measured temperature values;
- extracting a measuring signal, which is dependent upon the light signal, from the optical waveguide;
- and
- evaluating the measuring signal by means of the evaluation unit, in accordance with a temperature dependence thereof.
