要約(英語): This paper described partial discharge (PD) current waveforms in SF6 gas measured with a super high frequency wideband measurement system (SHF_PDPW system) with changing the electrode system to control the electric field utilization factor in order to statistically clarify the steeped pulse properties of the negative PD current pulses with a few tens picosecond order at the rising part, i.e. the minimum measured rise time was 30ps and the averaged ones were 45ps to 513ps depending on the utilization factor. The formation mechanism of such picosecond steeped rising part was discussed based on ionization process and electron movement in the critical electric filed by taking the influence of electron mobility as well as the frequency properties of the measurement system into consideration.
