Simulation of Electrical Stress Control System inside medium voltage Cable Termination using COMSOL Mph Software Platform.

This paper considers simulation of electrical stress system control for optimization of electrical stresses inside medium voltage cable termination. Optimization of electrical stresses is accomplished by inserting a layer with high permittivity value on the inner cable insulation. The study was carried out through simulations using software tool COMSOL Mph, entirely based on Finite Element Method (FEM). The main goal of this paper is to determine the optimal value of relative dielectric permittivity of inserted layer that results with most uniform electric field distribution on cable insulation.
