Downsizing medium or high voltage equipment requires the optimization of electric field distributions in the device and in the surrounding environment in order to master local high electric field strengths leading to partial discharges along the surface of the dielectric materials, prompting accelerated material ageing or in worse case dramatic failure. The purpose of this paper aims to compare for a cable termination both strategies namely resistive and capacitive (or dielectric refractive)
