Abstract

Since the production of PCB-containing fluids was discontinued, several dielectric fluid options have emerged. The author examines the most popular options and discusses their relative characteristics with respect to electrical properties, physical traits, use with switching operations, maintenance and environmental fate. The four predominant synthetic and natural materials that lend themselves to fire-resistant dielectric applications are discussed: organic polyol esters, silicone-based fluids less flammable petroleum oils, and synthetic hydrocarbons. These four materials are discussed
