This project is to study the distribution of the electric field of high voltage insulators Port bingo Posted daguerreotype 22 kV under the conditions fouling. The insulators, porcelain insulators are used rods (line post type) graphite rod and cup matches (pin post type) by simulating voltage and electric field. And tested in the test fouling a period of 1000 hours to keep the leakage current on the surface to analyze and compare test results. And test the severity of fouling by ESDD The results showed that the characteristics of the distribution voltage porcelain insulators insulation voltage cables that support the most valuable. And the nature of the electric field around the support line and the ground is high stress. The test found that the leakage current on the surface of the porcelain insulator leakage current on the surface will have more time to test. Caused by fouling in a cumulative increase in test time, making the leakage current increases. And to test the level of fouling was found. Insulator portfolio both players have a slight degree of fouling. The test is a test fouling from salt. The fouling which is more or less depending on the intensity of salt.
