Abstract
Polymer cable insulations tend to form space charges under DC stress. At the polarity reversal of the applied voltage, these space charges can cause field peaks, which can accelerate the electrical aging of the cable and even destroy the cable in the worst case. Due to the operational heating of the cable, a temperature gradient arises in the cable, which can lead to the electric field strength being reversed along the insulating path, which likewise contributes to the increase of the field peaks in the dielectric. A solution to the above mentioned problems could be to fabricate the insulation layer-wise perpendicular to the direction of the electric field with individual layers being of the same basic material but having different conductivities. The conductivity change can be controlled by means of conductive additives in the insulation. The aim of this work is to investigate such layer dielectrics under DC stress. The individual layers have different conductivities, which depend on the temperature and the strength of the electric field.
