In clean SF 6 gas-insulated power transmission systems significant pre-breakdown
discharges are rarely observed. This is so because the prevailing electric field is only
moderately non-uniform. In practical systems, however, conducting particle contamination
creates regions of highly non-uniform field. Initial ionization under contaminated conditions
takes the form of pre-breakdown discharges. An understanding of pre-breakdown
discharges is essential for evaluating the conducting particle effects and the insulation …
