    The paper describes a very-low-frequency (VLF) high-voltage test facility and includes the results of partial-discharge (corona) measurements undertaken on samples of electrical machine insulation. The samples were energized by means of a high-voltage generator, capable of producing alternating Voltages from 0.1 Hz up to power frequency. In order to eliminate spurious signals, partial-discharge me... View full abstract»

    The low frequency dielectric behavior of castor oil (a vegetable oil) has been analyzed quite exhaustively in the context of its application as impregnant in capacitors. For the sake of completeness and in order to understand the relaxation phenomena in this liquid dielectric, this high frequency dielectric study was undertaken. In order to compare its properties with a liquid dielectric used in s... View full abstract»

    An analysis of SF6 Paschen curves in the EHV/UHV range has been made. It is observed that the limiting value of critical electric stress is not the stress at which the apparent ionization and attachment coefficients are equal, that is, it is not the limiting value found for lower voltage treatments. Paschen departures, concluded to be a genuine phenomenon, are found to occur as an hyperbolic funct... View full abstract»

    This paper describes the effects of frequency, voltage, temperature and mechanical stress on the times to breakdown of XLPE cable insulation subjected to highly divergent fields. Temperature and mechanical stress reduce the times to breakdown but tests with increasing voltage and high frequency produced unexpected results which could not be explained by the existing theory of electrical tree growt...

    The effect of increasing the micabond resin content on the impregnation characteristics and electrical properties of a solventless epoxy resin impregnated groundwall insulation has been explored using small copper tube test samples. In this study, six different micabond materials, consisting of cycloaliphatic epoxy, bisphenol 'A' epoxy, epoxy-novolac, glycidyl-ester, and polybutadiene resins, were... View full abstract»

    Minimum creepage distances have been established for two classes of insulating materials which are used in marine electrical equipment and are susceptible and resistant to tracking. These distances are given for items of equipment with rated voltages of 500, 660, and 760 V as the result of tests on insulating elements contaminated in a naturai way during many years' service on ships.

    The mechanism of breakdown on an insulator surface contaminated with different species of salts under high voltage dc (HVDC) has been studied. Deleterious effects of nitrates on insulating surfaces were investigated in particular. Their influence on the structural integrity of insulators is discussed. View full abstract»

    This communication describes the complex permittivity of various mixtures of synthetic rubber and carbon (acetylene black, furnace black and channel black) in the microwave region. The effects of temperature on the complex permittivities are also noted for different concentrations of carbon. View full abstract»
