Influence of Ablation on Differential Arc Resistance
PLASMA PHYSICS AND TECHNOLOGY, 2017 The influence of ablation on the du/di behavior of an arc in a model gas circuit breaker was examined. Specifically the transition from a state without ablation in the nozzle towards states with ablation was of interest, since prior work indicated that for high currents the voltage becomes constant or du/di gets even positive if ablation is present ...
