1. Moisture: <50 ppmv for new gas, <150ppmv for gas in use in a breaker or GIS and 150ppmv is wet gas that needed drying or re-conditioning and 400ppmv is definitely dangerous to use. 2. Purity: <97% should be replaced, 97% and to 100% is good useable gas, 99.7 to 100% is new good gas. 3.

What is sf 6 Gas? | GasQuip - Sulfr hexafluoride 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. It is an incredible electrical insulator, which is why it is used as an arc quenching medium for higher voltage switch-gear. So what are the negatives? Unfortunately, sf 6 has been deemed as the most potent greenhouse gas that has ever been evaluated.

Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and
