The electrical tree propagation inside a solid insulating material is simu- lated in the present paper. The effect of a small insulating spherical particle inside the solid insulating material is investigated as far as the electrical eld is concerned. Laplace's equation is solved inside the solid insulating material setting the bound- ary conditions around the spherical particle. An attempt for comparison between the simulation results and experimental data from the technical literature is being made, trying to shed light to the physical mechanisms that are involved in the phenomenon.
