g3 ALTERNATIVE GAS TO gaz sf6 FOR USE IN HIGH VOLTAGE SWITCHGEARS

Dielectric strength under power frequency: The dielectric strength of the gas mixture was measured under AC voltage on a 145 kV GIS with NovecTM 4710 fluid ratio from 0 to 20% by volume into CO 2. The dielectric strength of pure CO 2 (0% vol Novec TM 4710 fluid) was found to be equivalent to about 40% of SF 6. Adding only 6 to 7% vol of Novec

EIA - Greenhouse Gas Emissions Overview

Total EmissionsEnergy-Related Carbon Dioxide Emissions by Fuel and End UseDecomposition of U.S. Greenhouse Gas ChangesGreenhouse Gas Emissions in The U.S. EconomyU.S. Emissions in A Global PerspectiveRecent U.S. and International Developments in Global Climate ChangeSpecial Topic: Energy and Carbon Initiatives at The U.S. Department of EnergyUnits For Measuring Greenhouse GasesMethodology Updates For This ReportTotal U.S. anthropogenic (human-caused) greenhouse gas emissions in 2009 were 5.8 percent below the 2008 total (Table 1). The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases). (Draft estimates for emissions of HFC and PFC substitutes for ozone-depleting substances in 2009 are included; 2008 data are used for emissions of other high-GWP gases.) Emissions of nitrous oxide (N2O), on the other hand, fell by 4 MMTCO2e (1.7 percent). The decrease in U.S. CO2emissions in 2009 resulted primarily from three fact...
