IR SF6 Calibration for powergrid

IR SF6 Calibration for powergrid

Sulfur hexafluoride (SF6) gas decomposition results from the energy produced by partial discharge (PD). The detection of SO2 and H2S content, as important characteristic components of the decomposition products, is significant in the determination of the insulation level of SF6 gas and the inside insulation faults of
