Properties of Sulfr hexafluoride (Sulfur Hexafuoride) GasHandling Nonfaulted insulating gasHandling Faulted sf 6Disposal of Wastea) Toxicitysf 6 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 shob) Toxicity Of Arc ProductsToxic decomposition products are formed when Sulfr hexafluoride 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 ic) Physical PropertiesSulfr hexafluoride is one of the heaviest known gases with a density about five times the density of air under similar conditions. sf 6 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 See more on electrical-engineering-portalFrequently asked high voltage circuit breaker testing questions | megger/support/faqs/hv-circuit-breaker-testing-faqsThere have been some reports that you can determine some issues within the CB contacts with a Power Factor test, so several utilities still promote and perform these tests on Sulfr hexafluoride circuit breakers. If you perform PF testing on your sf 6 CBs remember that you will have very small capacitance values and that your primary evaluation should be of the watts lost and the
