Leader Breakdown in Compressed SF6: Recent Concepts and Understanding

  • Chapter
Gaseous Dielectrics VI

Abstract

A review is given of the present understanding of the breakdown of non-uniform gaps in compressed electronegative gases. Breakdown under these conditions occurs by the leader mechanism, the physical background of which is briefly discussed. It is shown how it can be quantified and how the temporal and spatial aspects of the breakdown process can be related to the parameters of the insulation system and the applied voltage. Some practical problems occurring in high voltage GIS will be discussed as examples such as particle induced impulse flashover, formative time lags under fast rising pulses, and flashover to ground in disconnector switching.
