Abstract :
MOST ORGANIC INSULATIONS are not suitable for high voltage applications in contaminated atmospheres. Under surface arcing conditions, the organic constituents of the insulation decompose to form carbonaceous paths and the apparatus will fail by progressive creepage tracking. This article describes a proposed internal oxidation mechanism to eliminate formation of carbonized tracks upon exposure to surface electrical arcs.
