  • Sensitivity Characteristic Analysis of Adsorbent-Mixed Carbon

    With the development of the power industry, gas-insulated switchgear (GIS) has become more widely used in the power grid for its advantages of high reliability, small volume, and simple maintenance. Sulfur hexafluoride (SF 6) is used in GIS for its good insulating performance and arc extinction properties [1–4]. The manufacture, transportation and installation process inevitably result in defects in GIS equipment.
