  • High-precision density sensor for concentration monitoring

    Nov 01, 2013The dielectric strength of SF 6 mixtures, i.e., its insulation capability, depends on the density and the mixing ratio which can change as a result of various fault scenarios. For the mixtures SF 6 /N 2 and SF 6 /CF 4, the dielectric strength does not vary linearly with SF 6 content. Both mixtures give rise to synergism, i.e., an over-proportional influence of SF 6 on the insulation capabilityCited by: 10
