Abstract

The insulators located outdoors are subjected to external environmental factors such as humidity, temperature and pollution. The surface of the insulators may be subjected to high flow of leakage current during wet and polluted conditions. Due to this, a dry band arching occurs and when it extends for a longer duration it may degrade the insulator and ultimately lead to failure of the lines by initiating the insulator flash over. By conducting detailed study of the characteristics of the surface deposition layers contaminating the insulators The phenomenon of occurrence flash over in insulators that are polluted has been done by the study of the characteristics of layers of contamination deposited on the insulator surface in high voltage laboratories. This paper presents the simulation results of the epoxy coating on ceramic insulators. It was discovered that the magnitude of leakage current was significantly suppressed the coating. The flash over voltage is significantly enhanced by this coating. It was evident in the simulation there was a notable improvement of surface resistance of insulator after coating epoxy layer under a wide variety of environmental conditions in comparison with that of uncoated insulators. Overall experimental results indicated significant enhancement of insulator performance by applying epoxy coating. MATLAB Simulink is utilized for simulation studies and result comparison. ANSOFT SV2D Software is utilized for simulation studies and result comparison.
