    Three test methods that attempt to simulate the surface discharge conditions that exist on outdoor insulation are compared to each other and to one set of outdoor test results. The materials that are used for this comparison are filled and unfilled epoxide resins cured with acid anhydrides. Laboratory data for several other kinds of dielectric material also are included.

    The subject of this paper is the effect of partial discharges in a void on the performance of epoxy resin insulation. Theoretical and experimental investigations are reported that seek a relationship between measurable electrical quantities and a possible breakdown of the insulation. All experiments were done under controlled conditions with samples of quartz-power filled and unfilled epoxy resin ... View full abstract»

    An experimental study of the electrical properties of energy storage capacitors utilizing Mylarl polyester films has shown how the weight and volume of such capacitors could be reduced while improving reliability and energy density. Test data relate the lifetime of a capacitor to its operating voltage, discharge frequency, and temperature. The effect on life of percent current reversal and dielect... View full abstract»

    This paper deals with the stator winding insulation primarily of water-wheel generators and experience in Norway with this important part of rotating machines. Until 1962, first shellac, and later asphalt bonded micafolium were used as ground insulation of high-voltage machines. In 1962, a new insulation system based on a mica-splitting tape with modified polyester resin as impregnant was introduc... View full abstract»

  • Methods for Determining Thermal Transitions in Laminated Circuit Board Materials and Their Relationship to Cold Punchability

    Publication Year: 1968, Page(s):55 - 60

    Materials used in laminated circuit boards must be dimensionally stable at elevated operating temperatures and tough at room temperature to be cold-punchable. Certain polymeric materials with two or more thermal transitions have the desired combination of properties. Two novel methods for determining these transitions were developed. The first utilizes a single cured lamination of the circuit boar... View full abstract»
