Development of Flammability Criteria for Transformer Dielectric Fluids

摘要

With the recent ban on the use of polychlorinated biphenyls, it has become necessary to examine the fire safety requirements for electrical insulating fluids. The hazards are delineated and the magnitude of the transformer fire problem is assessed. The current fire code and standard test methods are shown to be inadequate. Approaches to fluid fire performance testing are presented, as is a basis for evaluating the economic impact of alternative fire safety strategies. The report concludes with recommendations for further work.
