Electrophotography of Internal Discharges in Dielectrics

Abstract

ELECTROPHOTOGRAPHS of discharges in air inclusions in dielectrics have been used for demonstrating the location and sequence of discharges during the short-time application of alternating and direct voltages1. A photographic film was enclosed between two disks of dielectric carrying silver film electrodes, one disk having a small cylindrical cavity adjacent to the photosensitive surface (Fig. 1). The sample was tested in conjunction with a discharge recorder2. Alternating voltage was applied for 1/25–1/10 sec.
