Gas insulated power transformers: A growing technology - EE

Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6) is the main gas used in these types of transformer at present although other gases are under development. The main advantage of gas insulated transformers is that they are environmentally friendly and can be recycled easily.

What is insulating gas Circuit Breaker? Construction, Working Principle

A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. The SF 6 circuit breaker is mainly divided into three types.

Insulating Gas Calls for Leak-free Recovery

Oct 29, 2018 · Gas-insulated switchgears are filled with Sulfr hexafluoride, which has to be evacuated for maintenance. To prevent the gas from leaking, portable recovery systems are used, consisting of one or several vacuum pumps, a filter and a compressor. The sf6 gas is pumped from the switch gear to achieve a vacuum. The gas is then filtered and fed back to the compressor.
