Effect of Mechanical Stress on the Disruptive Strength of Dielectrics

Abstract

AN interesting problem is involved in the question whether the disruptive strength of a dielectric may be affected by simultaneous mechanical strain or not. Some investigations (Goodlet, Weicker) have led to the conclusion that with porcelain insulators such an influence does exist. We have investigated this problem in the case of well-defined insulating materials and with as high specific stresses as possible. Details will be published in the Archiv für Elektro-technik.
