| Abstract | This dissertation applies a computational model to map the voltage distribution and electric field along dielectric devices in presence of a thin conductive layer on its surface. In the nature this thin layer may appear due to pollution deposition with environmental humidity. The base of this research are another studies found in literature with the same theme. The behavior of voltage distribution and electric field in dielectric devices has significant importance helping to determine possible regions where this devices present higher stress levels, causing partial discharges and possible damage to the accessories leading them to a failure condition. The applied model was implemented using FEM (finite element method) building an environment in COMSOL Multiphysics software and graphically representing each accessory through using AutoCAD. The present study was done in insulators made of glass and polymer, as well as spacers, under several pollution levels. The obtained results are consistent and show consonance with the whole theory involved in this research. |
