Abstract

Contamination flashover is a major concern affecting the reliability of power systems. Industries switched over from porcelain to polymers due to lighter weight and superior contamination performance. Polymers especially silicone rubbers (SR) helped considerably to eliminate the contamination problem. Bio contamination is a growth of fungi or other micro organism which colonize on the surface of the insulator. The paper presents results of the laboratory tests performed on polymeric insulators with and without bio contamination. It was observed that there is no effect of bio contamination on SR insulators, except that the part of insulator shed with algae formation lost its hydrophobicity and lot of scale formation was observed on all the insulators.
