Post-arcing recovery characteristics of vacuum interrupters under a high-rising rate of recovery voltage

This paper studies post-arcing recovery characteristics of vacuum interrupters under the action of a high rising rate of recovery voltage by analyzing waveforms of recovery voltage and shield potential. It discovers that in the post-arcing recovery, there are two processes: electric recovery process and plasma recovery process. The two processes relate closely with the performance of a vacuum interrupter. The success of the breaking of a vacuum interrupter will rely on the plasma recovery process.
