Arc Tracking in Organic Insulating Materials and the Comparative Tracking Index
One possible source of electrical failure in electronic equipment is arc tracking in organic insulating materials. Various tests have been devised to rank materials according to this property. The results of experiments evaluating the International Electrotechnical Commission test for comparative tracking index and the effects of varying certain test conditions on the resulting index are discussed.
