Abstract :
The authors present a recovery model that explains the plateau that has been observed in the recovery of gas-blown and static pulse-charged spark gaps. By careful analysis of the characteristic breakdown curves, it has been established that the initial recovery of the gap represents the return of the gap´s intrinsic breakdown strength, while final recovery corresponds to the return of an anomalously high overvoltage caused by significant statistical breakdown delay
