Maintenance sf6 pressure in circuit breaker Greenland

Maintenance sf6 pressure in circuit breaker Greenland,Properties of sf 6 (Sulfur Hexafuoride) GasHandling Nonfaulted insulating gasHandling Faulted gaz sf6Disposal of Wastea) Toxicitysf6 gas 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 sf 6 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.
