要約(英語): It has been reported that polymer nanocomposite materials have improved various insulating properties such as treeing resistance. The electric tree is a phenomenon accompanied by partial discharge (PD) and is one of the factors that determine the lifetime of polymer insulating materials. The effect of nanofillers on the electric tree is evaluated by an optical observation and the PD characteristics such as the charge amount or phase angle. Since the characteristics of PD original waveform reflects the condition of the discharge circumstance, it might be possible to evaluate the effect of the filler on the progress of electron avalanche based on the PD waveform characteristics. In this paper, the characteristics of PD waveforms in the electrical tree was analyzed using a measurement system with wideband frequency characteristics. Based on the waveform characteristics, the improvement of dielectric breakdown time by adding filler was discussed.
