Abstract :
Different outdoor insulating materials were exposed to marine pollution conditions and their surface conductivities were measured using an insulator pollution monitoring apparatus (IPMA), originally designed to measure surface conductivity on ceramic insulators. The current and conductivity values were used as a criterion to evaluate the different materials. EPDM with different creepages had dissimilar performances while silicone rubber insulators compared to EPDM and glass proved to be superior in having a lower surface conductivity
