    A numerical model is developed to simulate the curing and quenching of electrical distribution cables. The model considers a moving cable with possible three dimensional variations in properties and boundary conditions. Both heat and mass transport ort are included. A finite difference appmationoxiation is used to solve the governing equations. The key to the numerical solution is a Landau type tr... View full abstract»

    A numerical model is developed to simulate the curing and quenching of electrical stridistribution cables. The model considers a moving cable with possible three-dimensional variations ions in properties and boundary conditions. An exponential decomposition of the crosslinking agent is assumed; decomposition is then expanded in a Taylor's series to provide a means of continuously updating the prog... View full abstract»

    This paper presents the results of a study in which dielectric analysis was used to optimize catalyst concentration and minimize mold cycle time for an epoxy casting compound. The casting compound used was based on an anhydride cured hydantoin epoxy resin. Increasing the catalyst concentration to reduce mold time results in a reduced pot life. Using dielectric analysis, gel times and cure times we... View full abstract»

    This report presents an apparatus for continuously monitoring of hydrogen gas dissolved in transformer oil, in which a polyimide membrane is used to separate the hydrogen from the oil. The hydrogen is allowed to permeate through the membrane and contact a gas sensor every 72 hours. The characteristics of the permeation of the hydrogen gas through the polyimide membrane and of the detection of the ... View full abstract»

    This paper describes the influence of the electrolyte on tracking breakdown of organic insulating materials by the IEC (International Electrotechnical Commission) 112 Method. Two different kinds of electrolyte with surface active and non-surface active agents have been employed to study the influence of wetting agents on tracking breakdown. The effect of surface active agents on tracking breakdown... View full abstract»

    The accurate prediction of service life of extruded dielectric power cables from relatively short-term laboratory tests has been, and continues to be, a challenge for power cable engineers. Incomplete understanding of failure mechanisms and the effect of the many different in-service environmental factors, possible interactions between these factors, and the widely scattered nature of dielectric p...

    The radiation resistance of ethylene-propyleneethylidene norbornene terpolymer (EPDM) vulcanized with sulfur was studied. Several mechanical properties of original EPDM demonstrate maxima with irradiation. The property values at the maxima are observed to be a function of the gel fraction which was varied over a wide range by choice of the amounts of sulfur curing agent and accelerator. The deteri...

    Impulse and ac breakdown properties of transparent cast epoxy resins are reported having either a castin needle electrode or a needle-shaped recessed gold film electrode deposited by vacuum evaporation or sputtering, given a divergent electric field. Dielectric breakdown always initiates from the needle tip where the electric field strength is the highest. The dielectric breakdown process, which c... View full abstract»

    We have investigated the quantitative relation between the development of trees in polymethyl methacrylate resin subjected to ac voltage rising at a constant rate and the distribution characteristics of current pulses accompanying the development of trees. We also have estimated quantitatively the development of trees developed by a fixed value ac voltage using the results from ac voltage rising a... View full abstract»

    Pre-breakdown discharge currents in SF6 rod-plane gaps are measured under positive switching impulses and at different gas pressures. Four types of discharge currents could be distinguished, namely, single pulse discharges, multiple-pulse discharges, incomplete breakdown pulse, and corona-free direct breakdown. The effect of impulse magnitude, gas pressure, and gap geometry on the relative frequen... View full abstract»

    For twenty slightly different ethylene propylene (EP) insulated model cables, an 0.8 correlation coefficient was found between dielectric strength after aging and both tan6 after aging and the change with aging of insulation resistance constant (IRK). Aging consisted of 3.5 months immersion of 60 cable specimens in 90°C water with 2 MV/m 60 Hz electrical stress continuously applied. However, tan6... View full abstract»
