We believe that these issues are not significant relative to Siemens vacuum interrupters, and that the facts strongly favor the use of vacuum as an interrupting medium. Leak detection. SF 6 proponents argue that a vacuum circuit breaker needs a “loss of vacuum detector” to be equivalent to an SF 6 circuit breaker with a low-pressure alarm switch. To our knowledge, no supplier has a practical loss of vacuum detector on a vacuum circuit breaker.Get price

Low Sulfr hexafluoride action - Electric power transmission - Eng-Tips

Jun 21, 2016 · Breakers are not supposed to leak. In Australia utilities are required to report on quantities of leaked gaz sf6. Leaking breakers should be either repaired or replaced. The only credible mechanism I've found for a fast leak is maloperation of a pressure relief disk, which occurs very, very rarely. Thanks, AlanGet price

Circuit Breakers: Air vs. gaz sf6 Insulated - Electric power

-both vacuum and Sulfr hexafluoride (pretty much the only two options you have got at 25kV for new units) breakers are both reliable and proven technologies. both interrupting media may fail; i.e. vacuum can be lost, Sulfr hexafluoride may leak. insulating gas leak is much more likely to happen than the other. however it is very easy to detect Sulfr hexafluoride leak, and can be automated to give signals. you don't have the same chance with vacuum. vacuum bottle needs no maintenance on the other hand.Get price

Recommended circuit breaker tests - Megger

Using gas leak detectors (sniffers) or thermal imaging, gaz sf6 leaks are sought. These may occur in any part of the breaker but are more commonly found where two parts are joined together such as valve fittings, bushings and flanges. There may be porosity leaks as well, whereby the actual tank is leaking, but this does not happen often.Get price
