    Practical applications of vacuum as an insulator necessitated determining the low-pressure breakdown characteristics of long gap lengths of a point-plane electrode system. The breakdown voltage has been found to vary as the square root of the gap length. Further, with the point electrode as the anode, the values of the breakdown voltages obtained have been found to be larger than those obtained wi... View full abstract»

    Kraft paper is used for insulation in oil-immersed equipment such as transformers. While it has given satisfactory performance on electrical and mechanical properties, thermal degradation occurs due to temperature rise in operation. Examples of these kinds of the Kraft paper are cyanoethylated Kraft paper and amine modified Kraft paper. This report indicates the ability of insulating paper immerse... View full abstract»

    The electrical leakage of insulation exposed to moisture, particularly when salt deposits from a marine environment are also present, can degrade the performance of electrical and electronic equipment or render it inoperative until cleaned and dried. The effects of prolonged bulk moisture condensation on the surface electrical resistivities of some typical insulating materials and coatings have be... View full abstract»

    Electrical leakage across the surface of moist insulation can be reduced by the application of water-displacing fluids, and the susceptibility of many surfaces to leakage can be reduced by protective coatings. The water-displacing abilities and the protection provided by several agents were evaluated, and a superior formulation was developed. This formulation rapidly displaced moisture to restore ...

    New safety and environmental considerations in the design and operation of modern public transportation systems exclude the use of materials that can cause fire and ecological hazards. Therefore, the power transformers in trains and subway stations require new safer insulating liquids. The askarels or polychlorinated biphenyl (PCB) liquids have been classified as nonflammable, but recent investiga... View full abstract»

    The polarity effect on breakdown strength is a well-known phenomenon using a nonuniform electrode system, especially point versus plate electrodes. When the point electrode is negative, particularly, free electrons move in a liquid to form negative ions due to the possibility of electron attachment to electrically neutral atoms or molecules. Negative ions form space charges, by which field stress ... View full abstract»

    This paper outlines a method for testing the thermal stability of magnet wire by measuring the viscoelastic behavior of tubed fims obtained from magnet wire manufactured with standard equipment. It was found that there was a correlation between the glass transition temperature obtained from the mechanical tan ¿ versus temperature curve and the thermal class obtained from the IEEE No. 57 test meth...
