SF6 Breakers leak testing for testing

SF6 Breakers leak testing for testing

Most manufacturers don't recommend Power Factor testing SF6 dead tank circuit breakers. 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…
