ABSTRACT:
A semi-conducting pyrolyzed glass fiber layer equalizes the electrical potential on the exterior surface of an insulated conductor when the layer covers the surface. The layer prohibits the development of a corona discharge and bleeds off any electrical charge developed thereon when the layer is electrically coupled to a body having a known potential. The insulated conductor may be windings in a dynamoelectric machine.
