Abstract

he origin of electrical discharges in high voltage cables insulation probably can be attributed to many causes such as: overvoltage and the presence of impurities which have been introduced into the insulation during the manufacturing step. These impurities may lead to electrical field increasing thus to the formation of partial discharges. The purpose of this work is to determine the effect comes from cavities presented in Cross-linked Polyethylene (XLPE) on the electrical field, temperature and electromechanical pressure distribution into and around the cavity. The calculation of these constraints is performed by the resolution of LAPLACE equation using Finite Difference Method (FDM)
