Claim Text:
1. A device for controlling an electric field at a high voltage component comprising: an inner deflector to be electrically connected to a live high voltage part of the high voltage component; a resistive layer adapted for field controlling purposes, to be arranged along said high voltage component, and which at one position is to be connected to the live high voltage part of the high voltage component and at one end is adapted to be electrically connected to a grounded part of the high voltage component, the resistive layer having a nonlinear current-voltage characteristics; an insulating layer arranged on said resistive layer and extending at least from said one position towards said one end of the resistive layer while ending without reaching said one end of the resistive layer; and a semi-conducting or conducting layer arranged on the insulating layer and extending at least from said one position towards said one end of the resistive layer and past the end of the insulating layer, thereby defining an outer triple point at the intersection of the resistive layer, the insulating layer, and the semi-conducting or conducting layer, characterized in that the resistive layer has first, second, and third adjacent sections as seen from said one position towards said one end, wherein a portion of the first section extends below said inner deflector; and said insulating layer is in contact with, and extends above, said inner deflector.
