Detecting Insulation Gas leakage and quality

SF6 gas leakage harm. The installation of SF6 high voltage equipment of indoor space is generally closed, once SF6 gas leakage, the air circulation is extremely slow, toxic decomposition in the indoor deposition, not easy eduction, resulting in great danger when the staff enter into the SF6 switch room.

  • Gas Detector, Gas Leak Detector | ATO.com

    Wed, Jul 15 by ATO.com. A gas detector is an instrument used for the gas leakage concentration detection. The gas detector works mainly by using gas sensor inside to detect the presence of gas in the environment. The gas sensor serves as a reference point or scale which is the core part of gas leak detectors. Different gas sensors can react to different gases, so that the gas detector can detect

    May 24, 2020The gas sensors continuously monitor the environment to detect gas leakages. In doing so, they compare the measured sensor value with the threshold value obtained during the calibration. If there is an increase in the concentration of a gas beyond this threshold, it corresponds to a gas leakage and the same is reported to the control node.
