Surface deterioration and tracking breakdown in an atmosphere of low-pressure have been studied recently for a large number of organic insulating materials. In this paper, a possible process for surface deterioration and tracking breakdown of organic insulating materials due to glow discharge in an atmosphere of low-pressure is investigated with special attention to the decrease in volume with the time exposed to glow discharge.
Polyethylene (PE), polyvinyl-chloride (PVC), polystyrene (PS), polymethylmethacrylate (PMMA) and epoxy resin (EX) were used for the samples in this test.
Tracking and arc resistance test according to IEC 112 and ASTM D-495 methods were performed on the five samples used in this test so that the process for the deterioration and breakdown mechanism of organic insulating materials could be discussed.
