    This paper outlines techniques, developed over a number of years, for corona pulse height indication on meters and recorders. The use of (quasi-) peak-reading meters for indicating the level of the regularly occurring largest pulses in an insulation structure is discussed. The circuit combination of a loosely coupled RF transformer with a tuned Stoddart radio noise meter is shown to be a corona pu... View full abstract»

    To explore the fundamental concept concerning testing methods of corona resistance of insulating materials, some "roundrobin" tests with polyethylene have been performed by means of parallel-plate electrodes. The specimen films, degraded under the conditions of 6 kV ac impression and of static dry air, are examined with regard to weight, infrared spectrum, and other changes. From these results, in...

    The causes of corona in cast transformers are briefly discussed. Dissections of failed units and other observations have led to the conclusion that cracks along projecting margins of interlayer materials are sites of the most damaging corona. A test specimen is described which is intended to simulate corona in such cracks. Internal corona life data obtained with the new test specimen at 60 vpm and... View full abstract»

    The results of a study of the life behavior of a developmental capacitor of the synthetic film type are presented. The life is shown to be extremely sensitive to thermal history of the capacitor. Heating at 85°C for 100 days increased the life by at least 40 to 1. Progressive stress testing in which voltage is increased with time aided materially in defining this effect as well as in showing that... View full abstract»

  • The Electric Conduction in n-Hexane under Ultra Violet and Gamma Radiations

    In n-hexane, at fields up to 80 kV/cm, the dark conduction obeys Ohm's law, and the gamma-ray induced and ultraviolet photoinjected currents do not saturate for a wide range of temperatures. The induced and injected currents are proportional to the intensity of radiation. It is suggested that the dark conduction is associated with the presence of irremovable impurities and that the small fluctuati... View full abstract»

    The electric breakdown of nitrogen gas is determined using direct and 60-Hz voltage and impulse waves of both positive and negative polarity over the range of ¿ × 10 to 550 × 9000 microseconds. The electrode system is composed of a 1-inch diameter brass sphere and a 1¿-inch-diameter square-edged brass plane with a spacing between them of ¿ inch. The voltages are adjusted in small increments t... View full abstract»

  • Thermal Dependency of Viscosity, Power Factor, and Ion Content of Electrical Insulating Oils-III Predictions of Power Factor of Oil Blends Through the Concept of Ion Content

    With the objective of arriving at a better agreement, heretofore unattainable, between the power factor of a blended electrical insulating oil measured directly and that calculated from those of its components, the concept of "ion content," as initiated by Whitehead, was brought into play. As the term implies, "ion content," signifies a real and numerically addible quantity rather than an abstract... View full abstract»
