1) Qualitative method; The "qualitative method" to find the leakage site means that only the SF6 gas leakage site is determined, but the measurement of leakage speed and leakage cannot be measured. Such as SF6 qualitative leak detector (XP-1A), TIF5750A and other high accuracy, 4.6 g/year very small leakage can also be detected. It is composed of probe, sensor, analysis and processing circuit, sound and light alarm system, etc. The larger the air leakage, the faster the alarm sound and the more the number of flashing cells.

2) Quantitative method; "Quantitative method" refers to the accurate identification of the SF6 gas leakage site, and the detection of annual leakage speed and annual leakage rate. Quantitative methods rely mainly on instruments. Such as SFG6 quantitative leak detector (Winfoss-C1) SF6 infrared thermal image leak detector, SF6 laser leak detector, etc., the work is: high frequency ionization detection, infrared imaging, laser imaging and other principles.
