  • Characterization of GIS Spacers Exposed to SF6 Decomposition

    Characterization of GIS Spacers Exposed to SF6 Decomposition Products. Abstract: SF6 gas-insulated switchgear is a sealed system, but low- level contamination can accumulate and affect spacer performance. The degradation of a number of spacer materials exposed to either direct arcing conditions or arc by-products was investigated to correlate their surface molecular features with changes in electrical performance.
