Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

The insulating material used in the manufacture of modern insulating gas gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture. 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.

Measuring Dew Point and Moisture in Sulfr hexafluoride Gas

Sulfur hexafluoride (Sulfr hexafluoride) gas is an inert insulating gas of high dielectric strength and thermal stability, often used in the power sector for insulating high voltage lines, circuit breakers, transformers and other switchgear equipments. As sf6 is an inert gas, it can’t cause corrosion but in the presence of moisture it will cause formation of highly corrosive acidic by-products, such as Hydrogen Fluoride (HF) and Sulfur dioxide (SO2).

15 FAQs about Sulfr hexafluoride Gas and insulating gas Breakers - WIKA blog

In a dry environment, SF 6 can quickly break apart to capture free electrons, and then recombine. However, when moisture enters a breaker, the sulfur and fluorine molecules grab water’s oxygen molecules to form byproducts during high-temperature episodes. One result is that there is now less of the gas to act as insulator.
