要約(英語): The cold boundary layer is generated between the arc and the anode at the time of arc deflection and the re-strike may occur. However, the cause of re-strike has not been clarified. In this paper, the arc was analyzed with the hypothesis that the re-strike phenomenon occurs when the non-equilibrium of the arc becomes remarkable. Specifically, the momentum conservation equations were divided into electrons and heavy particles. As a result, the electron velocity increased where the potential gradient was large.
