Computer simulation for water treeing in polymeric materials

The phenomena of water treeing (WT) were simulated using finite-difference programs. The main parameters were investigated, and a comparison was made between the simulated results and experimental work. The point-plane model used to initiate and grow WTs is simulated. The programs calculated the equipotential distribution and the fields. Changing the permitivities of some parts in the grid used represented the propagation of voids in the model. Good agreement was obtained between simulation results and experimental work, some more simulation work has to be done.<>
