In predicting electrical tree growth behavior of
practical insulation materials under operating voltages, one must
consider the effects of mechanical tensile residual stresses,
electrical field stresses and the voids distribution to the electrical
tree growth. In this study a general model of electrical tree
propagation is firstly proposed depend on voids location in the
polymer, combines both the mechanical tensile residual stresses
and the electrical field distribution in the medium using charge
simulation method in combined with genetic algorithms to
describe the local damage features around the tree tip, and
enables this effect of compressive to predict the electrical tree
dynamic growth. The obtained results have been assessed
through comparison with available experimental data
