The numerical evaluation of the electric field in a cable termination equipped with stress grading materials, is carried out by adopting a model based on the electro quasi-static approximation of Maxwell equations. In such a model, the different nonlinear electrical properties of the stress grading materials, obtained from experimental investigations, are taken into account. The influence on the electric field distribution of the different characteristics (resistivity vs. applied field) is investigated, in order to draw useful information on proper field control
