Reviews: 14Estimated Reading Time: 7 minsProperties 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 opening.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 breaker where arcing or corona dis­charges have occurred in the gas. Evacuate the faulted SF6 gas from the circuit breaker and flush with fresh air before working on the circuit breaker.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 air and its cooling characteristics by convection are about 1.6 times air.d) Dielectric StrengthSF6 has a di­electric strength about three times that of air at one atmosphere pressure for a given electrode spacing. The dielectric strength increases with increasing pressure; and at three atmospheres, the dielectric strength is roughly equivalent to transformer oil. The heaters for SF6 in circuit breakers are required to keep the gas from liquefying because, as the gas liquifies, the pressure drops, lowering the dielectric strength. . The exact dielectric strength, as compared to air, var...See moreNew content will be added above the current area of focus upon selectionSee more on electrical-engineering-portal[PDF]SF6 Equipment Maintenance, Repair, and Replacement and epa.gov/sites/production/files/2016-02/documents/conf...PDF• Since beginning the circuit breaker replacement project in 2004, ITC has GE ATB-7 with free standing gas CT ppj, replaced or decommissioned 81 SF6 circuit breakers • The cost of breaker replacement ranges from $200,000 for a 120kV breaker up tofrom $200,000 for a 120kV breaker up to $500,000 for a 345kV breaker Mitsubishi 300SFMT-63E with slip-over non-gas CTs
