要約(日本語): The re-ignition of post arc at the current zero is caused by the transient recovery voltage. It is required to investigate gas flow rate and nozzle shape for improving current interruption performance. In this paper, the transient change of SF6 arc plasma in the current decay process was calculated using EMTF simulation.
