The top and the bottom of a ceramic spacer for sustaining an electrode gap contact with electrodes, in which there are triple junction points among the ceramic spacer, the gap electrodes and the atmosphere. Corona discharges formed at around the triple junction points may influence discharge characteristics for a spark gap. Additionally, the charges on the inner surface of the ceramic spacer, which are electrified by corona dischaeges, may act on the discharge characteristics. We measured V-t characteristic and residual voltage after operating a surge arrester with a spark gap. Based on the results, we evaluate affecting factors to V-t characteristics of impulse discharge .}, pages = {111--114}, title = {インパルス放電のV-t 特性に影響を与える因子}, volume = {49}, year = {2020}, yomi = {サコダ, タツヤ} }
