Essentials of gaz sf6 monitoring | TD Guardian Articles

01/01/2012. Because insulating gas has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world’s usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.Get price

U.S. Power Reliability: Are We Kidding Ourselves? | TD World

Difficult to Compare Reliability LevelsDifferent Consumer PerceptionsAccess Over ReliabilityThe European PerspectiveDr. Matthew C. Cordaro “All I know is that when I was on the EPRI board, I saw many of their studies that showed the U.S. system to be at least 99.99 percent reliable. The big question and goal for them was what we needed to do to move to 6 nines reliability.”–Matt Cardaro Stepping back from this and considering the big picture, it is really difficult to compare reliability levels unless the systems being considered are very similar in almost all respects, including the severe weather conditions they may experience. Even in the U.S. alone it is almost impossible to compare utility reliability, especially when different systems use different assumptions. and record and tabulate their indices in different ways. In fact. a number of utilities in this country do not even report their reliability results to a central collection agency or industry group. I have not studied the foreign data to any extent, but are all these countries measuring reliability in exactly the same way using the s...Get price

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...Get price

Why SF₆ emissions from the renewable energy sector should not

Increasing sf 6Global Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...Get price
