For PE insulated cables both the temperature difference ?T and the electric field coefficient ? have a significant influence on the electric field distribution because PE has a nonlinear electric conductivity which is approximately a function of the temperature and the electric field strength.

The coupled electric-thermal simulations are carried out for PE insulated HVDC-cables. The influence of the temperature and ? on the field distribution is investigated.The field inversion effect occurs both for the stationary and the time-dependent conditions.
