초록

20 years have passed since the first use of Korea-made polymer suspension insulators in distribution lines, and 24 million units have been installed in Korea. However, there are no inspection methods and replacement guidelines that can be practically used in the field. In this paper, to check the insulation condition of insulators and establish replacement guidelines, the lifespan of insulators was calculated by testing the insulators by used years. In addition, the effects of pollution in coastal and industrial areas, and insulation deterioration by shed damages were tested and analyzed, and replacement guidelines were suggested according to the shed damage. As a result of the test, polymer suspension insulators can be used for more than 30 years in the Korean power system environment, and replacement guidelines were proposed when 20 % of the shed is damaged because the damage to the shed has a greater effect on insulation deterioration than contamination. It is expected that the proposed replacement guidelines will be applied to the field to prevent power outages in the distribution system and contribute to improving power quality
