Abstract

This investigation was undertaken for the purpose of obtaining more information about the breakdown processes of perfluorocarbon gases under electrical stress. Corona characteristics were obtained for the CF4 and C3F8 gases over a considerable period of time in the presence of additives. The substances used for additives were those for which there was existing evidence that they could function as corona inhibitors. Thus, additives showing an ability to act as inhibitors of free radical reactions were chose, since the decomposition reactions could produce free radical fragments. A comparison of the effect of these additive sin the two perfluorocarbon gases could yield some information on the predominant bond cleavage in C3F8, since only carbon-fluorine bonds can be broken in CF4. Some improvements were made in the apparatus for manipulating the gaseous compounds and the additives. After several unsuccessful attempts, an apparently satisfactory method of fluoride analysis was found. This method could be used for future investigations of perfluorocarbon gases, since a quantitative knowledge of the fluoride ion formation could yield valuable information for understanding the chemical reactions of perfluorocarbons under electrical stress.
