insulating gas circuit breaker maintenance | TD Guardian Articles

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using sf 6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of sf 6 circuit breakers was the lower voltage classes of 72kV and 145kV.

Essentials of Sulfr hexafluoride monitoring | TD Guardian Articles

Because sf 6 has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world’s usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.

Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

In this issue, we discuss the use of gaz sf6 (sulfur hexafluoride) gas in medium-voltage switchgear. gaz sf6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses Sulfr hexafluoride gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
