    Experimental observations have been made on resin samples containing one single cavity and on micaceous high voltage insulation. The results conflict with the generally accepted mechanism of voltage variation of the electrical characteristics of such samples, which mechanism is based on the influence of internal partial discharges. One different dissipative mechanism, namely the interfacial polari... View full abstract»

    Several contributions to the study of empirical correlation between tip-up and insulation life are reviewed. In addition to the published literature some previously unpublished field measurements are cited. Some investigators report favorable correlation while others report the contrary. Our own experience on two different insulation systems indicates that the extent and the nature of correlation ... View full abstract»

    Bridge measurements of the dissipation factor tip-up at increasing voltage are generally assumed to give a correct measure of discharge intensity. It has been shown earlier that even when the tip-up is entirely caused by discharges it does not represent an unambiguous measure of discharge intensity, because ¿tan¿ depends on both the amplitude and the phase of the discharge pulses. The validity o... View full abstract»

    The paper describes application of integral approach to the numerical computation of fields in a multi-dielectric, three-dimensional system. The accuracy of the method has been studied by taking a simple example of parallel-plate electrodes containing two-layer dielectrics. The use of fictitious point charges has been found to be quite successful in the analysis of fields in and around a disc insu... View full abstract»

  • Improved Unitary and Multicomponent Gaseous Insulators

    Publication Year: 1978 , Page(s): 31 - 36
    Cited by:  Papers (12)

    Improved unitary and multicomponent gaseous insulators are systematically designed according to detailed knowledge of fundamental electron-molecule interactions. Knowledge of the electron attachment and electron slowing-down properties of dielectric gases/mixtures as functions of electron energy is shown to be especially significant. On the basis of such knowledge it is possible to improve the gas... View full abstract»

    The electric field of a point charge or a spherical conductor in three or more dielectric layers on a plane conductor is calculated ated by digital computer. That of a point charge is calculated by the method of images, and that of a spherical conductor by the charge simulation method in combination with the method of images. Numerical examples show that the potential, the field strength, and the ... View full abstract»

    A mineral oil and a synthetic oil consisting of aromatic constituents were each irradiated by ¿rays at both room temper-ature ture and abo°t 70OC; the degree of the degradation was analyzed by means of gas chromatograms. The results showed that synthetic oil consisting of diarylalkane hydrocarbons has superior radiation-resistant properties. In addition, when mineral oil containing sulfur compou...

  • Lichtenberg Figures on Various Electrical Insulating Materials

    The surface discharge on insulating solid materials was recorded by a camera with high speed films. This simple method was found to be useful for the investigation of the surface discharge on various insulating materials. Lichtenberg figures on the surface of seven types of insulating material were determined by this method. The starting voltage for the formation of Lichtenberg figures was found t...

  • The Influence of Water on the Electric Strength of an Ethylene-Propylene Insulation

    Needle tests on samples of ethylene propylene copolymer based insulation after water absorption have confirmed that the short term life at voltage is extended by the presence of water. Also it is shown that water is desorbed more rapidly than absorbed and this is accompanied by a reduction in electric strength. This result implies that tests on cables after water immersion should involve a short d... View full abstract»
