Abstract

The deposited pollution on the insulaters surface in overhead Transmission Lines and also its characteristic is one of the effective factors on insulators electrical behavior. The pollution on insulators surface is Non-uniform due to the wind direction. So, less contamination is in the same direction wind. Also, the pollution is different throughout the insulators length and in near high and low voltage electrodes. Therefore, the deposited contamination on insulators is non-uniform and can be considered two forms of longitudinal and Fan-shaped uniform Pollution/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">non-uniform Pollutions. In this paper, the influence of uniform Pollution and also the effect of three states for pollution expansion (%15, %25, %35) and four states non-uniform contamination degree (1. 5, 3, 6, 13) with longitudinal and Fan-shaped, under different humidities, on the flashover voltage different 20 kV silicon rubber insulators, have been studied. According to the obtained results from laboratory tests, the increase of non-uniformity contamination degree has significant effect on the behavior of the insulators under different uniform Pollution/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">non-uniform Pollution, so that the flashover voltage has decreased between 8. 8 to 42. 21 percent in all the insulators.
