Breakdown characteristics of the statistical time lag and the formative time lag of flashover have been investigated by applying a flat-top nanosecond pulse to dry-air insulated gaps at atmospheric pressure. As for the formative time lag of the sphere gap, the formative time lag was inversely proportional to the electric field. The statistical time lag(More)
The characteristics of multichannel arc gap are investigated experimentally. The gap comprises 12 or 24 steel needle electrodes and a brass rod electrode. We examined the characteristics of the number of arc channels when the parameters below were changed: (a) rising rate of voltage pulse applied to the gap (b) length of feeders which transmit voltage pulse(More)
