Abstract
A device for controlling an electric field at a high voltage component including a resistive layer for field control, an insulating layer arranged on the resistive layer and a semi-conducting or conducting layer arranged on the insulating layer. The three layers meet at a triple point where the insulating layer ends. An interface between the resistive layer and the insulating layer makes in the triple point an angle to the semi-conducting or conducting layer of 60°-120°.
