The polymeric insulating materials treated in this work are Bakelite (Ba), Polyvinylchloride (PVC) and Polystyrene (PS). Behaviour of creepage current under some typical ratings of high voltage a.c. according to the IEC standard 587 is introduced. The insulation against h.v. tracking is dependent on the amplitude of the applied voltage stress, changes in the degree of contamination and on its size on the insulation surface. Erosion process due to the chemical reactions between pollution and insulation surface during the creepage stress has been investigated. Results suggest that the peek to average current ratig during creepage stress up to the end point of h.v. tracking may be used to determine the value of erosion depth of polymeric materials.
