A high-voltage component, having a first end and a second end, whereby the
first end is on a high-voltage potential with respect to the second end.
An insulating part, is arranged between the first end and the second end,
and an optical fiber is integrated in the high-voltage component and
extends from the first end to the second end. A capillary extends from
the first end to the second end and is arranged within the insulating
part. The inside diameter of the capillary exceeds the outside diameter
of the fiber, and the fiber is arranged within the capillary. The
capillary includes a protective medium to achieve a dielectric strength
in the capillary, which dielectric strength is suitable for the operating
conditions.
