Abstract

This contribution reports on experimental investigations dealing with the impact of different combined aging parameters like electrical field strength, conductor temperature, and test duration on the dielectric relaxation behaviour of full-sized model cables with cross-linked polyethylene insulation. The evaluation of time-domain isothermal depolarisation current measurements turns out that characteristic properties of a third order exponential decay function exhibit different trends depending on the nature of the various aging factors.
