high voltage insulating gas Inspection Prospect
2018/11/22System Functional Tests. 1. Visual and Mechanical Inspection. Testing and maintenance of protective relays always begins with a thorough visual and mechanical inspection. If the circuit to be tested is in service, one relay at a time should be removed (if applicable) so as not to totally disable the protection.
hv sf6 gas Low pressure
2012/2/14At first thinking, it seems possible to open the breaker with very low or zero SF6 pressure, after it is completely isolated from the line and busbar sides, and grounding also provided at both ends (remote end breaker would be opened first). It is because after isolation, there would be no need of insulation and arc quenching, provided by SF6.

Chemical formula: SF₆Melting point: −64 &C; −83 &F; 209 KMolar mass: 146.06 g/molSolubility in water: 0.003% (25 &C)OverviewSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earth's troposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium and high voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.
