where can I get sf6 Analysis for cables

To check the quality of the SF6 gas i.e. the insulation of the CB, it is recommended to perform a moisture and purity test on the SF6 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 SF6 circuit breakers.
