Sulfur Hexafluoride Gas Leakage Monitoring and Early-Warning

Jul 14, 2020 · A sulfur hexafluoride gas leak can cause serious health concerns if effective measures are not adopted in time. Therefore, in this study, a sulfur hexafluoride gas leakage monitoring, early-warning, and emergency disposal model was established. First, taking the main transformer chamber of an underground transformer substation as the research object, a 3D-model was built, and a numerical simulation was performed.Get price

Sulphur Hexafluoride | Edinburgh Sensors | Gas Detection

NDIR sensors for measuring SF 6 leaks. Sulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.Get price
