Get Price5/4/2014Sulfr hexafluoride 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.
Get PriceComponents Gas density control Since the dielectric strength of the switchgear and the breaking capacity of the sf 6 circuit-breaker depend on the density of the sf6 gas gas, a gas density relay is installed to control gas density and detect leakage. Voltage transformer PASS can be equipped with conventional GIS inductive voltage transformers. . Similarly to Current Transformers,
Get Priceinsulating gas Transmitter. The Sulfr hexafluoride transmitter is ideally suited for the gas measurement of sulfur hexafluoride in the field of high voltage engineering. The transmitter can be used both as a gas leak detector and to monitor the gas quality in gas-insulated switchgear (GIS) or transformers. Request a Quote.
