Abstract

Shortly after the end of World War II, scientists and engineers started to report on the mechanism of dielectric breakdown of solid organic insulating materials. During the first ten years, considerable effort was directed toward the effects of corona (partial discharges) on the surface of candidate materials with little attention paid to internal degradation leading to breakdown.
