    As in many other electrotechnical fields, the research work and the early realizations in the cable field during the second half of the last century were the germ of most of the techniques developed in the 20th century. For more than 70 years, paper impregnated with oilresin compounds or simply with oil, prevailed as an insulating material in cable manufacturing, though rubber insulated cables wer...

    The long-term transient and steady-state currents produced in Schefflera stems by polarizing voltage steps of various amplitudes, and the subsequent depolarization currents, are investigated. Concurrent measurement of the voltage drops in the vicinity of the positive and negative electrodes permits the elimination of the electrode impedances. The conductance of the stem itself is obtained as a fun... View full abstract»

    Partially conducting coatings, used to suppress discharge activity in the slot region of high-power turbogenerators, are subjected to long-term electrical, l, thermal and mechanical stresses which may eventually reduce a coating's effectiveness. To study their long-term properties, permittivity and dc conductivity measurements were made on graphite loaded samples with a modified alkyd-resin base o... View full abstract»

    Further theoretical analyses show that it is the physical parameters of the guard gap region which give rise to the anomalous phenomena observed in dielectric loss measurements using a three-electrode system. A Wagner or similar guard balance, which is generally used to make the potentials at the guard and the guarded electrodes identical in magnitude and in phase, may reduce the errors caused by ...

  • Computation of Electric Fields and Study of Optimal Corona Suppression for Bushing-Type Insulators

    Publication Year: 1986, Page(s):41 - 51
    Cited by:  Papers (6)

    Using the Runge-Kutta and Newton-Raphson methods, the electric fileds on the bushing-type insulator surface covered partly by a corona-suppression semiconductor coating with a field-dependent resistivity have been computed for semiconductors having various resistivityfield ield (p-E) characteristics. The field distribution along the insulator surface is strongly dependent on the p-E characteristic... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (756 KB)

    This paper describes the development of a compact and stiff thyristor-controlled HVDC source for investigating the characteristics of contaminated insulators. It has been realized by placing revers reverseparalleled thyristor units in a 3.3 kV line on the primary side of a HV transformer. Since the circuit parameters are difficult to be chosen freely, optimization of the control parameters of the ... View full abstract»

    The main properties of a newly developed impregnant ant for high voltage power capacitors are given. This new liquid, a mono dibenzyltoluene blend (M/DBT), has a very high degree of aromaticity. The results of many tests carried out both on model and large capacitors are reported. A screening test using a transparent micro-model of an all-film capacitor has been used to study the properties of the... View full abstract»

    A very sensitive device has been used to try to detect the emission of light during the initial phase of the growth of water trees. No emission was detected, either before the onset of growth of the trees or during the propagation, contrary to what is observed in electrical treeing. This experiment eliminates light emission as a tool to examine initiation and propagation mechanisms in water treein... View full abstract»

    This paper presents the most significant results of multiyear research carried out in order to evaluate the thermal endurance properties of insulating materials. The thermal life model, proposed by Dakin, has been analyzed and compared with the experimental data; the importance of the selection of properties and their end points (failure criteria) on the shape and location of the thermal endurance...

    The results of measurements of internal partial discharge intensity generally are used to assess the risk of failure of electrical insulation due to internal discharges. However, with the use of present definitions ions of discharge intensity, there is as yet quatenadeuate information for specifying acceptable levels of intensity. The effectiveness of indicators of discharge intensity has been che... View full abstract»

    A technique for relating measurable electrical quantities with energies dissipated inside a void in highly electrically stressed insulation is presented. It is based on measuring, for each apparent discharge level qe, the algebraic sum of the external energy pulses of all discharges having a value qe and occurring over some cycles of test voltage. Theoretical investigations show that the results o... View full abstract»
