    There is a need to better understand electrical ageing of solid insulating materials in dry environment and discharge-free conditions. Photons emitted by a stressed material give evidence of the generation of highly reactive molecular states that could control degradation reaction. View full abstract»

    It is worth noting that, with a few exceptions, the efforts to develop dielectric systems, especially for the LTD superconducting cables, are lagging behind the intense efforts to develop more efficient HT superconducting materials, tapes, and conductors. The results presented here and reported in the literature confirm that lifetime is usually greater for cryogenic insulation, and thus the impuls... View full abstract»

    Discusses models and their possible implication in the interpretation of the relaxation spectra of polymers, particularly involving the concept of order/disorder systems. Furthermore, some examples of the application of the Dissado-Hill model have been provided in this work to explain quasi-dc (QDC) conduction processes, which have been observed in crosslinked polyethylene (XLPE) and low density p...

    By about the year 2010, an EHV power transmission system will be built in China in response to the remarkable growth in demand for electric power. The new voltage level should be chosen to take into consideration the previous and the next voltage levels. Referring to the experiences in the other countries, if the transmission capacity increases 4-7 times, a new voltage level will appear that is 1.... View full abstract»
