manufacture SF6 decomposition detection system For determining the quality

IEC60480 44 specifies the test standard for the detection of SF6 SF 6 decomposition products using FTIR. Zhang et al. 45–50 conducted a series of FTIR studies on the decomposition products of SF6 SF 6. The studies were based on the principle of White-Cell. They designed a gas cell with a 20-m-long path length, which was matched with FTIR.
