Dielectric breakdown characteristics of clean oil
Conference Record of the 1992 IEEE International Symposium on Electrical Insulation, 1993 The dielectric strength of highly filtered and dehydrated oil was investigated with AC and impulse voltages. The influence of particles on breakdown strength is discussed, taking into account the particle content factor. The scale effect of superclean oil, which was obtained from a modern cleaning system, is studied from a statistical viewpoint.
