Abstract

Insulations are the most important part of high voltage equipment such as cables and machines. Therefore the study of the condition and mechanism of failure of high voltage insulations is important. This paper studies the electrical constraints within an XLPE insulated cable containing micro-cavities. The purpose of this work is to determine by simulation the distortions caused by micro-cavities on the electric field distribution in the insulating layer of cable. The calculation of these constraints is performed by the resolution of LAPLACE equation using Finite Difference Method (FDM) because of its simplicity in the symmetrical and two-dimensional systems, which corresponds perfectly in the case of cables which can be considered as cylindrical systems with axial symmetry.
