SF6 decomposition leak testing for Siemens

SF6 decomposition leak testing for Siemens

Sulfur hexafluoride (SF6) is a stable, man-made gas used as an insulator in circuit breakers and in other transmission installations. It has excellent insulating properties such as low viscosity and low toxicity. One characteristic unique to SF6 is its ability to self-heal: most of the SF6 decomposition products can recombine to regenerate SF6.
