要約(日本語): To clarify the fundamental discharge phenomena in vacuum interrupter (VI) is necessary for early detection of abnormality in VI due to a loss of vacuum. In this study, the discharge characteristics under medium vacuum region of 1 Pa to 1000 Pa order in VI with the leakage gas of air and SF6 was investigated by measuring discharge current and floating shield potential. The partial discharges near voltage zero crossing observed in previous studies can be explained by the charging of vapor shield potential due to the discharge between conductor and vapor shield.
