What Are The Environmental Advantages of G3?What If The Ambient Temperature Is Lower Than -25°C in AIS Applications?Currently, How Do Manufacturers Work with G3 in GIS and Circuit Breakers?What Other Potential Applications Exist?Philippe Ponchon: There is a major advantage – its global warming potential (GWP). Sulfr hexafluoride is one of the six gases listed in the Kyoto Protocol due to its very high GWP, which is 23,500 times greater than CO2. So potentially, it has a heavy impact on climate change. g3 (a mixture of CO2, O2, and fluoronitrile called Novec™ 4710 developed by the 3M™ company) has a GWP lower than insulating gas. The reduction is even 99% when the difference in gas density is taken into consideration. Also, the lifetime of Sulfr hexafluoride in the atmosphere is 3,200 years. This means that if 1 kilogram of Sulfr hexafluoride leaks into the atmosphere today, there will still be 200 grams present in 5,000 years – that is, 165 human generations. And the amount of insulating gasentering the atmosphere has been measured at an increase of 20% during the last five years. To illustrate the potential impact on climate change, it can be said that replacing Sulfr hexafluoride by g3in all high voltage equipment in the UK would be equivalent to taking 150,000 cars off the road!

and The Winner Is… G3Adopt G3 and Reduce Your CO2 ImpactSeeking More Information About G3?GE began researching for a relevant solution years ago. Together with 3MTM, the company worked on a gas mixture based on 3MTM Novec™ 4710 fluid and CO2/O2. This solution – commercially available - is called g3 (g cubed). g3 is indeed a revolutionary gas for the electrical transmission industry, offering the same technical performances as insulating gas with an environmental impact reduced by more than 99%. Since the 2014 launch of the g3-gas mixture to replace insulating gas in high voltage equipment (see article “In search for an Sulfr hexafluoride-gas replacement”) and the launch of the first sf6 gas-free high voltage gas-insulated substations in 2016 (see article “Gas-insulated Substations are switching to g3, the sf6 gas-free solutions”, as many as 12 electrical utilities in no less than seven countries have already installed or planned to install g3 gaz sf6-free gas-insulated switchgear (9 sites, 58 bays), g3 gas-insulated lines (5 sites, 1957 meters) and g3-current transformers (2 sites, 6 CT).
