    A rapid measurement of thermal deterioration of oil-immersed papers by mass spectrometer and gas chromatograph is described. A special assembly was developed using a mercury diffusion pump and automatic Topler pump to extract a very small quantity of generated gas from the oil and to collect it in a reservoir. The gas collected by the above assembly is analyzed by mass spectrometer and gas chromat... View full abstract»

    A new calorimetric method for measurements of insulation aging rate is introduced. The method is based on measurements of the heat flow caused by the heat absorbed or liberated in aging reaction. In isothermal conditions, this heat flow is proporticnal to the reaction rate. The instrument is sensitive enough for reactionrate measurements down to the service temperatures of materials. Using an appr... View full abstract»

    New synthetic resin insulation systems have been established in Japan, as in Europe and the United States [2], and have a history of almost fifteen years. The research work of authors, initiated in 1949, led to the completion of the unsaturated polyester insulation system called SLS insulation. Outstanding performance was obtained as of 1957 when this new insulation system was applied to large rot... View full abstract»

    The volume of oil under the highest stress has been shown to correlate well with the measured breakdown voltages of transformer oil in different electrode systems. The determination of the volume of oil that is most highly stressed in a given electrode system is not however an easy matter. It involves the location of equistress or equigradient surfaces followed by computation of the oil volume con... View full abstract»

    This paper describes the effects of adding small concentrations of organic additives (anthraquinone, benzophenone, and diphenyl) to transformer oil on its gassing characteristics under different gas phases (H2, N2, O2, and air), different stresses and different temperatures. The results show that there exists an optimum concentration for each of the additives used. The optimum concentrations were ... View full abstract»

    Calculating the life expectancy of electrical insulation is an interesting application of Arrhenius's law. Bussing's analytical treatment is derived for the simple case of life at constant temperature. Its extension to variable temperature conditions is explained as is the application of the same techniques to calculating mechanical failure due to creep and capacitor failure due to electrode diffu...
