  • Nanomaterials Based Gas Sensors for SF6 Decomposition

    Authored by Xiaoxing Zhang. The insulating medium used in gas-insulated switchgear is SF6 gas, which has been widely used in substations. Energy generated by discharge will cause the composition of SF6 and generate characteristic component gases. Diagnosing the insulation defect through analyzing the decomposed gases of SF6 by chemical gas sensors is the optimal method due to its advantages.Cited by: 1
