Events Associated with Zero Current Passage during the Rapid Commutation of a Vacuum Arc

  title={Events Associated with Zero Current Passage during the Rapid Commutation of a Vacuum Arc},
  author={Susan E. Childs and Allan Greenwood and J. Sullivan},
  journal={IEEE Transactions on Plasma Science},
Events associated with the rapid commutation of the current in a diffuse vacuum arc are explored experimentally and analytically in the short interval during which the current is brought to zero and the recovery voltage is established across the residual plasma. A brief pause of the order of 100 ns is observed between the passage of current through zero and the point where the recovery voltage starts to rise. Current zero is interpreted as the instant when the ion and electron currents are… CONTINUE READING
