Abstract
A high voltage arrangement for a high voltage power system has an insulating structure which reduces the creep path. The insulating structure is arranged around the second conductor and has a continuous extension in an axial direction from a first end thereof providing insulation of essentially the entire length of the second conductor to a second end around the bushing portion, which second end extends around the bushing portion at least to a point where an electric potential of an external surface of the bushing portion is at most equal to the average of the potential of the first conductor and the potential of the interfacing plane when the high voltage arrangement is in use.
