  • NDIR SENSORS FOR SF6 MEASUREMENT - smartGAS

    The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute SF6 quantities in indoor air. No matter what SF6 concentration has to be measured under what conditions – smartGAS offers the suitable NDIR sensor. SF6 is the strongest greenhouse gas and therefore the most harmful to the environ-ment.

  • Myth About SF6 Gas In Electrical Equipment

    Apr 12, 2021 · 21. How much SF6 (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203)
