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 Sulfr hexafluoride gas itself. All sf6 gas breakers are sealed and incorporate a molecular sieve type desiccant to maintain moisture to extremely low levels. Although power factor testing of a insulating gas gas circuit breaker will not cause any harm or detrimental affects to the device, misleading results may be witnessed.Get price

What is Sulfr hexafluoride Gas? | GasQuip - gaz sf6 Equipment and Training

Characteristics of insulating gas Gas. Sulfr hexafluoride Gas is a colorless, odorless, non-flammable, and harmless to humans and animals in low quantities.
