Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

The main insulating materials are Synthetic filament wound epoxy insulating tubes, Hollow core insulators (porcelain or composite), and the sf6 gas gas itself. All insulating gas breakers are sealed and incorporate a molecular sieve type desiccant to maintain moisture to extremely low levels. Although power factor testing of a gaz sf6 gas circuit breaker will not cause any harm or detrimental affects to the device, misleading results may be witnessed.Get price
