SF6 Multi-Analyzers | T&D World humidity in the gas, which can get in through improper gas handling or leakages in the gas compartment, is a significant quality indicator. In the event of discharges, the humidity acts as a reaction partner and, alongside the discharge energy, is a determining factor in the extent of the resulting concentration of decomposition products.
How Circuit Breakers Ensure Safety & Reliability of Power ... GCB, all the components are placed inside modules filled with sulphur hexafluoride or SF6 gas. Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium of sulfur hexafluoride (SF6), having excellent dielectric and arc-quenching properties.
