2021-3-16Sulfur Hexaflouride Possession of Purchases. Due to its extreme global warming potential, the California Air Resources Board (CARB) passed a regulation restricting Sulfur Hexafluoride (SF6) gas

The high-voltage switchgear is an electrical equipment based on circuit breakers. It means that the manufacturer connects the relevant high and low voltage electrical appliances (including control appliances, protective appliances, and measuring appliances), bus bars, current-carrying conductors, Insulators, etc. are assembled

2021-2-1SF6 Gas Density Monitors: Normal pressure gauges are not suitable for this monitoring operation because with the same gas density, the gas pressure is dependent on the gas temperature in closed gas systems. This dependency is is specific to the used gas and is shown in a vapor pressure diagram with lines of

2021-3-16The filling gas in the gas insulated switchgear is SF6 and N2 normally, so the maintenance cost is much higher than AIS. Also, when transporting, bumping is difficult to avoid. If a solid object on the switchgear has cracks due to bumps, the gas

A new gas also means new tools. Gas monitoring and handling equipment has been developed or adapted in parallel with the work on the switchgear itself. g3 monitoring Gas monitoring is done with g3 as it was with SF6. Traditional sensors (temperature-compensated pressure switches) have only to be adapted to the updated pressure.
