SF6 concentration sensor for gas-insulated electrical

The use of SF 6-N 2 gas mixtures in gas insulated electrical switchgear (GIS) is becoming more wide-spread. This is motivated by the reduction of environmental impact associated with SF 6 emission and the increasing nuer of GIS loed in low temperature environments where pure SF 6 cannot be employed. We present a cost-efficient sensor system that tracks gas composition based on a
