Effect of Pollution Layer Thickness on Electric Field Distribution along a Polymeric Insulator
Veröffentlicht in 2015
Electric field distributions along a polymeric insulator under wet and contaminated conditions were studied in this paper. To study the effect of pollution layer conductivity and thickness on the electric field distribution along a standard polymeric insulator, simulations were carried out with commercial simulation package COMSOL Multiphysics. Pollution layer was modeled as a conductive water layer and conductivity was varied from 10-6 to 10-3 S/m. Similarly, thickness of pollution layer was varied from 0.5 to 2 mm in steps of 0.5. It was observed during simulations that electric field intensity increases with increase in pollution layer conductivity and thickness.
