    Abstract: A device for controlling an electric field at a high voltage component includes an inner deflector electrically connected to live voltage component; a resistive layer adapted for field control, arranged along the high voltage component, and electrically connected to the live high voltage component and electrically connected to a grounded part, the resistive layer having a nonlinear current-voltage characteristics; an insulating layer extending but ending without reaching the end of the resistive layer; and a semi-conducting or conducting layer arranged on the insulating layer and extending towards 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. The resistive layer has first, second, and third adjacent sections, wherein a portion of the first section extends below the inner deflector.
