Abstract

THIS paper, written by F. Meyer of the General Electric Co., was allocated for reading to the Institute of Electrical Engineers on November 23 and is now published. The author discusses the everyday fluid insulators used for electrical apparatus, particularly with transformers, and advances suggestions for improving the British Standard Specification (148, 1933, Insulating Oils for Electrical Purposes). In addition he discusses the properties of chlorinated diphenyls, perhaps the commonest non-inflammable liquids used for this purpose, which are known in America under the technical name 'pyranol'. The particular requirements of oils suitable for condensers are also considered.
