Investigation of Electric field distribution on a 33kV polymeric insulator under polluted conditions using Finite Element Method

In areas with high levels of pollution and vandalism, one remedy suggested is to place polymeric insulators on high-voltage transmission networks.. They are widely used although having some advantages compared to their light weight and ease of handling, which is an appealing aspect, they also come with a wide range of financial and operational issues. The electric field distribution simulation results for medium voltage composite insulators that have been constructed ideally are presented in this work in both polluted and unpolluted environments. The Comsol Multiphysics tool conducted simulations for both standard and optimized insulators. This paper's major goal was to examine the impact of electric field distributions in relation to pollution circumstances. The influence of the pollution layer's conductivity and thickness was examined together with the electric field's dispersion. According to the modelling findings, significantly contaminated ecosystems had higher maximal electrical field stresses than clean or slightly polluted ones did. The outcome of this investigation will further our understanding of how polymeric insulators behave in diverse contaminated settings.
