Behaviour of water droplets on polymer surface

The flashover of polymeric insulators in artificial contamination tests shows that, the discharge on a fully contaminated insulator follow the leakage path along the surface of the insulator. The presence of water droplets and contaminated layers intensify the electric field strength on the surface of polymeric insulator. Therefore, the study of electric field distribution on polymeric insulators under wet and contaminated conditions is important. The water droplets play an important role in pollution flashover and ageing of polymeric insulator. Therefore study of water droplets on Polymer surface is very important and hence studied.
