SF6

The critical importance of SF₆ gas detection in power networks

  Since sulphur hexafluoride (SF₆) is colorless and odorless, leaks are not perceptible without specialized detection equipment. Reliable gas detection systems are therefore critical to enable timely intervention and safeguarding maintenance teams working in GIS installations, notes Gaurav Bawa.   Read more
