sf6 circuit breaker probe training in Electrical Applications

sf6 circuit breaker probe training in Electrical ApplicationsProperties 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. Ib) Toxicity Of Arc ProductsToxic decomposition products are formed when SF6 gas is subjected to an elec­tric arc. The decomposition products are mec) Physical PropertiesSF6 is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. SF6 showd) Dielectric StrengthSF6 has a di­electric strength about three times that of air at one atmosphere pressure for a given electrode spacing.

(Types and Operation electrical4u/types-and-operation-of-sf6-circuit...20/03/2013Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical
