The key difference between g3 and gaz sf6 is that g3 is a gas mixture while insulating gas is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “ The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.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
