Electric conduction breakdown and partial discharges in dielectric fluids. I. Partial discharges

Some studies have suggested that there may exist a relationship between conduction and electrical breakdown. Before such a correlation between these phenomena and partial discharges (PDs) can be investigated, it is necessary to produce reproducible PD data. For this reason an investigation was undertaken to study the behavior of some well-defined dielectric fluids such as phenyl xylene ethane, ditolyl ether, mono and dibenzyl toluene, and perfluoro polyether in the pure state. Some preliminary results of this study are presented, and their significance is discussed in detai
