Sulfr hexafluoride - smartGAS Mikrosensorik | 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.Get price
