UHVDC Transmission

A new transformer developed for the world’s first ultra high-voltage DC transmission systems (UHVDC) has successfully completed final testing. It is the first transformer for the new 800 kilovolts (kV) HVDC in China. Today’s HVDC transmission systems normally operate at a standard transmission voltage of 500 kilovolts. HVDC systems can transmit power over much greater distances and at considerably reduced loss than is possible with AC systems.

To achieve this 60-percent increase in peak voltage capacity, Siemens had to develop a range of entirely new technical solutions for the new 800-kilovolt HVDC transmission system. One of several major challenges facing the company’s development engineers in Nuremberg was a lack of any defined standards for this scale of system. Due to the very high operating voltage, for example, they had to design exceptionally effective insulation systems. Therefore, in order to achieve the needed insulating clearances in air, the two valve bushings through which the current flows from inside the transformer to the converters are 14 meters in length. To construct the 800 kV transformers, a new, specially air-conditioned production hall had to be built to prevent the insulation from absorbing moisture from the atmosphere during final assembly. Similarly, the test facility in the Nuremberg factory had to be adapted to accommodate the tremendous increase in voltage when carrying out final acceptance testing on the new transformer.(CAN U ABLE TO FIND OUT TWO PERSONS ARE STANDING NEAR TO IT...IMAGINE ITS SIZE)

INTEL core i9

                                     Immediate obsolescence is an age old problem in the computer industry, but it doesn't look like the upcoming Core i9 "Gulftown" processor is going to do anything to solve it. Word is from early benchmarks of the upcoming Intel processor is that it bests the current Core i7 at the top of the heap with speed gains as large as 50% -- directly in line with its addition of two cores on top of the Core i7's existing four. Of course, six 2.8GHz cores aren't quite as exponentially helpful when applied to non-optimized tasks, but with most major modern software development aimed at better utilizing multiple cores, the core overkill of Core i9 will likely prove increasingly useful over time. At the start, however, Core i9's improvements will come at a premium: 130W power consumption instead of 95W in Core i7, and of course a high-end only price tag to match.

POWER SECTOR IN INDIA(30%Loss-40,000 Crore loss )

The power sector could trip the country’s growth story if states do not check the losses of power utilities that totaled a staggering Rs40,000 crore.


“The power sector is particularly important if we wish to achieve 9% growth...Total loss in 2009-10 is estimated at Rs40,000 crore...Unless corrected, it will make the whole power sector unviable,”


India has one of highest transmission and distribution losses in the world. It lost 30% of the total power produced (over 160,000 MW) in transmission and distribution, which in monetary terms is estimated at Rs45,000 crore for the fiscal year ending 31 March 2010.
