    A method for calculating complex fields between lec electrods in conducting media is proposed. It is shown that there exist dual relationships between a complex field due to an alternating current source in a conducting medium and an electrostatic field due to a charge in a dielectric medium. If a solution to the problem of an electrostatic field is known, then the solution to the corresponding pr... View full abstract»

    Experimental studies of conduction processes in various insulators at dc and ac voltages up to 50 kHz show that frequency dependent dielectric losses contribute to critical power densities Pk1 and Pk2 independently and equally to resistive losses in the insulating materials which arehar characterized by a spatially inhomogeneous charger carrier transport. The upper critical power density Pk2 marks... View full abstract»

    Flashover characteristics of rod-rod and rod-plane electrode configurations in transformer oil are studied for extremely long gap lengths in the range of 150 to 1000 mm under conditions of lightning impulse, switching impulse, and alternating current voltages. The relation between flahsover voltage and gap length and the polarity reversal effect for switching impulse voltages are described in deta... View full abstract»

    An ice or ice-silica compound system is attractive for electrical insulation at cryogenic temperatures. A sample of ice without silica was found to have a breakdown strength of 0.3 MV/cm for ac voltages, and 0.6 MV/cm for impulse voltages. The breakdown strength of an ceicesilica compound system was 0.7 MV/cm for ac voltages. There were no visible macroscopic cracks in the sample, but microscopic ... View full abstract»

    This paper describes an investigation into the growth of electrical trees in polyethylene by the simultaneous measurement of light intensity and partial discharges. The emission of light has been studied using an image intensifier. A comparison of the results obtained for different types of trees has been made. The detection of discharges shows that each category of tree is characterized by a part... View full abstract»

    The breakdown characteristics of polymethyl methacrylate (PMMA), immersed in high pressure gaseous media such as CCl2F2 and mixtures of CCl2F2 and N2, subjected to both positive and negative direct voltages with ripple contents of various percentages are reported. The peak breakdown voltage of the solid dielectric immersed in the gaseous media decreases with increasing ripple content and pressure ... View full abstract»

    Materials, including silicon dioxide (SiO2), are degraded by SF6 gas dissociation products. Changes in surface resistivity and volume resis tivity due to SF6 dissociation products were investigated in SiO2-containing insulating materials, for instance porcelain. It was found that surface resistance and volume resistance of these materials decrease with exposure of SF6 gas dissociation products and... View full abstract»
