    Ultrasonic techniques are useful for the detection and location of partial discharge or corona sources associated with HV power apparatus, particularly oil-filled power transformers. Measurements are commonly made using narrow-band transducers operating in the frequency range from ~20kHz to ~300 kHz, and occasionally at higher frequencies for which there is little published information. Because of... View full abstract»

    A wide-band peak voltage detector is presented, which is used for measuring partial discharges in submarine telecommunication cable systems. For high-voltage discharge detection of simple dielectric geometries or complete power filters, the wide-band detector is suitable for laboratory or factory use. A low-cost low-resolution amplitude-distribution analyzer can be assembled by combining several d... View full abstract»

    Vacuum insulation with cylindrical ceramic spacer insulators has been studied with respect to changes of its ac flashover voltage with time. The distributions of times to failure, which were found to confirm Weibull's distribution, were used for plotting the regression curves for times up to 350 h. The results show that even at rather low stresses the flashover voltage decreased in time. This phen... View full abstract»

    The results of a series of experiments performed in sulphur hexafluoride gas for pressures up to 100 psig (0.68 MN/m2) are described. Uniform field electrodes and both dc and standard impulse voltages were used. The volume resistivity of the dielectric material used was considered to be a significant parameter, and for this reason some graphite loaded coatings were Also used. The results indicate ...

    The dielectric properties (ac and dc) and the viscosity of an insulating oil and its aromatic and nonaromatic fractions are compared. The results indicate that the properties of the whole oil cannot be determined ined from the properties of its components and their concentrations. A model based on dipole interaction is presented and is shown to- account for the observed results. View full abstract»

  • A Study of Pressboard Monodimensional Impregnation with Transformer Oil and Its Influence on Dielectric Strength

    The knowledge of the impregnation mechanism of porous solid insulation seems useful to ascertain the reaching of optimum insulating properties, but the problem has been scarcely dealt with in the literature, perhaps because of the high analytical difficulties resulting if a theoretical approach accounting for all the relevant phenomena is taken. A simplified mathematical model of pressboard monodi... View full abstract»
