SF6 Gas Leakage TestMaintenance of Hydraulic Operating MechanismMaintenance of Pneumatic Operating MechanismWe can do SF6 gas leakage test either by soap water or a SF6 detector. But the latter is more preferable. If we detect any leakage, we must rectify the same preferably in presence of competent engineer of the manufacturer. At the same time we can fill up the CB with the new SF6 gasto makeup the pressure loss. Again sometimes, the leakage may be so small, that we cannot detect it even with the help of a gas detector.

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.

  • SF6 circuit breaker maintenance | TD Guardian Articles | USA

    The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.
