    A different approach in thermal evaluation of hermetic insulation is presented. A random-wound bifilar coil of enameled wire, with or without varnish, is aged at a series of elevated temperatures while in a refrigerant atmosphere. Dielectric properties are measured repeatedly at each aging temperature and aging rates are calculated. From rate data at various aging temperatures, energies associated... View full abstract»

    This paper gives the results of an experimental study of the dependence of conduction currents in transformer oil on temperature and hydrostatic pressure (10-760 torr) using direct fields up to 680 kV/cm. Results of measurements with degassed oil and oil containing dissolved oxygen suggest that electrons move through the liquid partly as free electrons and partly as negative ions. The dependence o...

    The electric breakdown of air and nitrogen was determined in test cell diameters of 2, 4, and 6 inches using electrode systems of a one-inch-diameter brass sphere to 1 4-inch-diameter square-edged brass plane and also using a sharp-pointed tungsten electrode to the same size brass plane. Also, these electrode systems were used in free ambient air with no enclosing cell. The electrode spacings used... View full abstract»
