Power factor testing of insulating gas circuit breakers | TD Guardian

The main insulating materials are Synthetic filament wound epoxy insulating tubes, Hollow core insulators (porcelain or composite), and the sf 6 gas itself. All Sulfr hexafluoride breakers are sealed and incorporate a molecular sieve type desiccant to maintain moisture to extremely low levels. Although power factor testing of a Sulfr hexafluoride gas circuit breaker will not cause any harm or detrimental affects to the device, misleading results may be witnessed.Get price
