SF6 decomposition pipes for powergrid

OSAHighly sensitive SO2 photoacoustic sensor for SF6 ...A compact ppb-level SO2 photoacoustic sensor was developed for the application of SF6 decomposition detection in electric power systems. The selection of the SO2 target spectrum is discussed in detail in the infrared (IR) and ultraviolet (UV) spectral regions. Based on the result of the spectrum selection, a small-sized UV-band
