SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

Properties of SF6 (Sulfur Hexafuoride) GasHandling Nonfaulted SF6Handling Faulted SF6Disposal of Wastea) ToxicitySF6 is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is re­duced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks should be purged out after openi…b) Toxicity Of Arc ProductsToxic decomposition products are formed when SF6 gas is subjected to an elec­tric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do not breathe the vapors remaining in a circuit brea…c) Physical PropertiesSF6 is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. SF6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air. The heat trans­fer coefficient of SF6 is greater than ai…See more on electrical engineering portalReviews: 14Published: 2011/1/4Estimated Reading Time: 7 minsHOW TO MAINTAIN SF6 CIRCUIT BREAKER 123seminarsonly123seminarsonly/Seminar Reports/048/93245921 How to Maintain...PDF fileInternational Journal of Scientific Research Engineering Technology (IJSRET) Volume 1 Issue1 pp 030 035 March 2012 ijsret.org ISSN 2278 0882HOW TO MAINTAIN SF6 CIRCUIT BREAKER 1Snigdha Sharma, 2Hemant bharadwaj,
