Flashover Voltage of Some Electronegative Gases in Underwater Sound Transducers

Abstract

The flashover voltage of PZT ceramic in nitrogen and in several electronegative gases, especially sulfur hexafluoride and the perfluorocarbons, was tested. The results are related to electrical breakdown in sonar transducers. Empirical equations are presented for computing the flashover voltage of these gases and air mixtures with these gases as functions of pressure and distance. The effects of water vapor in air on the flashover voltage of ceramic are reported. The chemical breakdown products of the gases caused by moderate arcing are described. (Author)
