Patent ID: 7373056

Claim:
A high-voltage component comprising; a first end and a second end, wherein under operating conditions the first end is on a high-voltage potential with respect to the second end; an insulating part, which is arranged between the first end and the second end; and at least one optical fiber, which is integrated in the high-voltage component and which extends from the first end to the second end, wherein the high-voltage component comprises: at least one capillary, which extends from the first end to the second end and which is arranged within the insulating part, wherein: the capillary has an inside diameter that exceeds the outside diameter of the fiber, the fiber is arranged within the capillary, the capillary has a protective medium to achieve a dielectric strength in the capillary, which dielectric strength is suitable for the operating conditions, the outside of the capillary is enclosed by a capillary coating in order to protect said capillary against mechanical stress, the capillary is designed and arranged in the insulating part such that thermo-mechanical stress, which the insulating part exerts on the capillary during the curing process of the insulation part, leaves it undamaged, and a current sensor and/or voltage sensor operating electro-optically, magneto-optically or piezo-optically, in that the fiber is a polarization-maintaining fiber.
