How to Detect sulphur hexafluoride Monitor for transformers

The C901S monitor can detect the first appearance of an SF 6 leak into the oil and quantify changes in leak severity over time. Calisto DGA monitors are ideal for assessing the health of transformers in GIS facilities. They provide accurate DGA data no matter if SF 6 leaks into the oil. And the C901S model specifically enables timely maintenance decisions if ever such a leak arises.

  • Leak Detector Measure Concentration of Sulfur Hexafluoride

    LumaSense SF6 Leak Detector is able to measure the total concentration of the Sulfur Hexafluoride gas in a monitored enclosure where the switchgear (or other SF6-filled equipment) is tested. It is critical to detect leaks and improve "gas-tightness" during the testing period to ensure the equipment will perform in the field.

    The high sensitivity and very small lower detection limit enable the 50 ppm sensor to detect even minimal sulphur hexafluoride leaks with absolute reliability. Another typical application for the highly sensitive FLOW EVO SF 6 sensor (50 ppm) is detection of SF 6 in environmental simulations. Since sulphur hexafluoride is not present in the atmosphere and non-flammable and non-toxic, it is used in very small concentrations as a tracer gas for real-time analyses of the spreading of fire gases
