sf6 gas Sensors | Gas Insulated Switchgear (GIS) | smartGAS

During the operation of gas-insulated switchgears the purity of the SF 6 decreases and the protective function of the SF 6 gas is reduced. This is the result of arcs that occur during switching of the high-voltage switchgears and cause chemical transformation of the sulphur hexafluoride molecules.

The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.
