Abstract
A wet chemical procedure is described that is suitable for investigati ng the degradation of sulfur hexafluoride (SF6), used as an insulating medium in high-voltage and ultra-high-voltage power equipment. It is based on the alkaline hydrolysis of S-IV species present in aged SF6 a nd subsequent spectrophotometric determination of sulfite through its capability to accelerate the autoxidation of Co-II to Co-III in aqueou s azide solution. Results showing the ageing of SF6 as a function of t ime are presented.
