Weavers after a long test tracking analysis of GIS equipment whether newly installed or installed and operated for a long time, more or less there will be leakage, but the amount of leakage of newly installed equipment is small, its annual leakage rate should not be greater than 1%.

Leaks from indoor equipment can be detected with SF6 qualitative and SF6 quantitative leak detectors. The best detection method is to use SF6 infrared imaging detector for detection. It can accurately detect the leak of small gases, and the leaking gas will be displayed as "black smoke" on the screen, so you can determine whether there is SF6 gas.

The SF6 infrared thermal image leak detector uses innovative technology, which makes the leaking gas of SF6 gas invisible to the naked eye visible and can be recorded in any image memory.
