in gas form in 2 kg cylinders for gas-to-gas operations, such as topping up or filling instrument transformers. GE’s partners have also developed special gas carts (for both small and large volumes) for the filling and recovery of gas mixtures, similar to the SF 6 equipment standards that users are already familiar with (Figure 4).

Trojan Dryout Systems Mission. Our mission is to provide transformer owners and transformer maintenance contractors with oil filtration and oil processing equipment that is easy and safe to operate, highly effective, and with a low ongoing cost of operation.

Nov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.

In gas insulated transformer, gas is used as the insulating and cooling medium for the transformer. Sulphur Hexafluoride, SF6 is the gas used in gas insulated transformer. These transformers are adopted due to its environment-friendliness, non-explosive and non-flammable in nature.

A circuit breaker in which SF6 under pressure gas is used to extinguish the arc is called SF6 circuit breaker. SF6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The SF6 circuit breaker is mainly divided into three types
