Hi am Deepak i would like to get details on extra high voltage transmission line in india filetype ppt ..My friend Rajat said extra high voltage transmission line in india filetype ppt will be available here and now i am living at Bareilly and i last studied in the college/school SDS Inter College and now am doing B.tech in EE branch i need help on

Electricity often travels over very long distances to reach urban load centres. For example, the distance between Baie-James region—where water from the Grande Rivière ends up after driving the turbines in eight power stations–and Montréal is about 1,000 kilometres as the crow flies. However, the farther electricity must travel, the greater the risk that part of it will be lost on the way. Since utilities invest heavily in the high-volume transmission of power over long distances, they take special steps to limit these transmission losses.When moving large volumes of electricity, it’s better to increase voltage instead of current intensity (amperage), in order to reduce energy losses and limit the total cost of transmission (building additional power lines, for example). A large portion of the power generated by Hydro-Québec is transmitted using 735-kV lines. Without these high-voltage lines, the landscape would be cluttered with towers. One 735-kV line is equal to four 315-kV lines, the next voltage level down.
