insulating gas circuit breaker maintenance | TD Guardian Articles

The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV. As Sulfr hexafluoride breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing gaz sf6 as the line-to ground dielectric insulation.

Frequently asked high voltage circuit breaker testing

To check the quality of the sf 6 gas i.e. the insulation of the CB, it is recommended to perform a moisture and purity test on the sf 6 gas. There have been some reports that you can determine some issues within the CB contacts with a Power Factor test, so several utilities still promote and perform these tests on insulating gas circuit breakers.
