  • Service High Voltage Products gas monitoring systems

    properties of sulfur-hexafluoride or SF 6 make it invaluable for the high-voltage switchgear industry. However SF 6 is also a greenhouse gas, over 20,000 times more potent than CO 2. Hence, accurate monitoring of SF 6 leakages become absolutely vital.

    Oct 22, 2020History of SF 6. SF 6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that SF 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20 th

  • The basics of high voltage switching equipment in power

    Dec 08, 2020For extreme cold temperature applications (ambient temperatures between −40&C and −50&C), the SF6 gas is typically mixed with another gas, either nitrogen (N2) or carbon tetra fluoride (CF4), to prevent liquefaction of the SF6 gas. The selection of which gas to mix with the SF6 is based upon a given site’s defining critical criteria
