Abstract :
Recent developments in research on insulating oils are largely concerned with methods of testing and evaluation rather than with the development of new or better petroleum products. Without adequate test methods (other than long time service tests), no criteria are available for distinguishing between good and bad liquid dielectrics. Unfortunately, a large amount of isolated individual research, by independent companies, has not been published and is, therefore, not available to oil chemists.
