Electricity substation - ! GlobeCore Oil purification medium-voltage distribution substations, metal-enclosed switch gear may be used and no live conductors exposed at all. For higher voltages, gas-insulated switch gear reduces the space required around live bus. Instead of bare conductors, bus and apparatus are built into pressurized tubular containers filled with sulfur hexafluoride (SF6) gas.

THE CARBON DIOXIDE LEAKAGE FROM CHAMBERS MEASURED …· In plant chamber studies, if Co2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates: consequently, it is critical that Co2 leakage be determined. Sulfur Hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakage in the chambers occurs via pressure ...
