    Jul 30, 2019The breakdown statistics of vacuum and SF6 gaps differ. Although a vacuum gap in principle has a very high breakdown voltage, there remains a very small probability of breakdown at relatively moderate voltage. Vacuum gaps are known to show spontaneous late breakdown, up to several hundreds of milliseconds after current interruption.
