Thermal Dependency of Viscosity, Power Factor, and Ion Content of Electrical Insulating Oils-II Characteristics of Blended Insulating Oils

Electrical characteristics of blended insulating oils are of interest not only in the actual high-voltage engineering practice, but also in the understanding of the basic theory of dielectrics. By simple mathematics, this study reveals some of the fundamentals of the behavior of insulating oils, offers approximate but useful methods for computation and prediction of power factor for any composition of oils within the useful temperature range, and opens new approaches for further study concerning the physics of insulating oils.
