  • High-Precision Density Sensor for Concentration Monitoring of

    Jan 01, 2012 · The gas mixtures investigated, SF 6 /N 2 and SF 6 /CF 4 , are common gaseous insulation fluids for low- temperature gas-insulated switchgear (GIS) and gas-insulated lines (GIL). In this equipment continuous gas concentration monitoring is required over long periods of time, since the dielectric strength of SF 6 mixtures depends not only on the density but also on the mixing ratio and faults caused by e.g. leakage or condensation can change this ratio and thus compromise the proper operation.
