Abstract
For environmental reasons the quantities of sulfur hexafluoride (SF6) used in high voltage equipment must be reduced by mixing it with some lower-risk gases: N2 for instance 1_5. The stability of such mixtures under electrical constraints during operation must then be checked and compared to that of undiluted SF6. Among the various types of stress to which SF6 is subjected, sparking may occurs, especially in substations. The discharges degrades the gaseous insulator as well as other struck materials (as solid insulators); so the sparking-induced decomposition of SF6 or SF6-N2 mixtures was to be studied in presence of additives (vaporized insulator, O2, H2O).
