  • SF6 gas measuring devices – Synergy Power Systems

    Measuring instruments are used to monitor ambient air, trace leaks and to measure the SF6 quality of electrical operating equipment. The SF6 gas must always be pure since humidity and toxic or corrosive decomposition products in circuit breakers impair the insulating properties of the gas.

  • SF6 concentration sensor for gas-insulated electrical

    2014-2-1The 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 number of GIS located in low temperature environments where pure SF 6 cannot be employed.
