Sf6 purity analyzers in switchgears - Switchgear Content

May 20, 2020 · Photo from RH system company gas analyzer model 973. Sulfr hexafluoride gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, sf6 gas is supplied in pressurized bottles or liquid tanks. The gas of these bottles has a minimum degree of purity of 99.9% and may possess the following impurities according to IEC 60376:

Measuring Dew Point and Moisture in sf6 gas Gas

Sulfur hexafluoride (insulating gas) 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).

Power factor testing of high-voltage Sulfr hexafluoride circuit breakers

At the time of production, Sulfr hexafluoride gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required. The insulating material used in the manufacture of modern gaz sf6 gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.
