Experimental Study on Aging of Polymeric Insulators by Dip Method

Polymeric insulator is the best alternate to Porcelain insulator under polluted conditions. Polymeric insulators perform well under polluted conditions. But aging of polymeric insulator is an unsolved problem. Standards included 1000 hours and 5000 hours test for assessing aging of polymer insulator. Both the tests were withdrawn and Tracking wheel test is being introduced in the standards. An alternate test for Tracking wheel test is being proposed hereby. The results are encouraging.
