The comparison of electric field perturbations by water inclusions in linear and nonlinear XLPE insulation

Abstract

The mathematical modeling results of low-frequency electric field inhomogeneous distribution and the total current density in the high-voltage polyethylene insulation with water micro-inclusions has been performed. The comparison of calculations results for linear and nonlinear problem formulation has been made. The evaluation of solid insulation degradation in strong electric fields has been performed.
