    Measurements are reported on the effect of specimen size and filler content on the electrical-impulse strength of epoxy polymer. For unfilled polymer, the strength was found to decrease more rapidly with increasing thickness than with increasing area. But the incorporation of as little as 1 percent by volume of filler removed the thickness effect and lowered the impulse strength. The area effect w... View full abstract»

    The flashover voltage and current of a water column, which provides a suitable resistive surface for discharge propagation, have been calculated considering the heating and constriction of the column. Theoretical predictions are compared with experimental results obtained under dc applied voltage for: jet lengths of 2 ⩽ L ⩽ 5 cm, initial unit length resistances of 3 ⩽ r View full abstract»

    A new theoretical model for high-field electric conduction and breakdown in dielectric liquids based on the theory of filamentary single injection is presented. The model is based on the following postulates. 1) The high-field conduction is mainly due to electronemission from the unavoidable asperities on the metallic cathodesurface and is confined in one or more filamentary paths, in which thecur...

    An outline is given of the nature of partial dischargesoccurring in insulation structures, in particular in oil impregnatedconfigurations. It is suggested that conventional discharge measuringsystems are not always able to assess significant parameters becausemuch of the available information is inevitably discarded during thehigh-voltage tests. A mobile computer-based data-acquisition system hasb... View full abstract»

    A method of investigating partial-discharge phenomena andtheir effect on polyethylene is described. A physical study was carriedout with air at atmospheric pressure and gaps between 2 and 14 mm.It is shown, that with this range of gaps and with dielectric walls, astreamer process appears as in the case of a positive point and a metallicplane.The evolution of the polyethylene samples after the agin...

    A new analysis analogous to recent work for parallel-plateelectrodes is presented using a unipolar ion-mobility conduction modelbetween concentric cylindrical or spherical electrodes. Exact solutionsare obtained for the transient behavior of the bulk electric-field andspace-charge density distributions and for the terminal current-voltage(I-V) time dependence. The analysis is generalized to handle... View full abstract»

    The nature of metal/SF6 reactions under direct-current(dc) simulated circuit-breaker conditions has been examined in orderto explore: 1) the identity of the process(es) responsible for the differentmagnitudes of electrode consumption for various pure metals; 2)the factors determining the different rates of reaction with SF6observed for different metals. It is concluded that high-current arcerosion... View full abstract»

  • The Influence of Solid-State Cohesion of Conditioned Metal Electrodes on the Electrical Strength of the Vacuum Gap

    The solid-state cohesion of metals maintaining electricalstress across a vacuum gap appears to determine the magnitude of theelectric strength of the vacuum gap. For conditioned electrodes(presumably free of adsorbed and oxide layers) under direct-voltage conditions,higher electric strengths are associated with metals having highmetal-metal bond energies and vice versa.

    Photographs have been taken of microdischarges whichoccur when a metal particle approaches an electrode in an electricallystressed oil gap. The total stress in the oil between the particle and theelectrode is similar to the breakdown stress recorded for oil gaps ofsimilar spacing. View full abstract»

    Charge or RIV techniques for corona (partial discharge)have been used in factory tests of high-voltage oil-filled equipment.Such tests have also been used in the field. More recently, measurementsof evolved gas have been made as well.In the laboratory, the effect of corona in oil has been determinedlargely by measuring gas evolution using the Pirelli test, in whichdischarges take place in oil vapo...
