Abstract :
Techniques for maintaining pressure on oil-impregnated paper insulation in high-voltage cable are discussed, with emphasis on the design and application of fluid pressure systems and components. Methods for quantitative determination of pressure drop, oil demand, and oil requirement, about which there has been much written, are omitted here. An aim of this paper is to establish a pumping plant design which has the broadest application, and to classify the significant variations from this base.
