Efficiency Improvements in Transformers by Adoption of New Magnetic Material | Original Article
Since independence in India there has always been shortage of electricity and at no point of time we have been able to meet the peak demand. The gap between the demand and generation can be bridged/minimized by either improving the installed capacity or reducing the consumer demand. The gap between availability & demand is of order 6% as on date. If we take into account the issues like environment pollution and global warming, the preferred option is to increase the energy efficiency or minimize the consumer demand, as in the other alternative particularly in India, where thermal generation dominates, increased environmental pollution is inevitable .The paper covers design of transformer using a new technology superior magnetic material with thin sheets of lazer grade or amorphous core. Iron Boron Silicon amorphous alloy is a unique alloy whose structure of metal atoms occurs in random patters as opposed to conventional CRGO steel which has an organized crystalline structure. The paper covers design of distribution transformer using conventional material and the new technology improved core materials. The reflection on the no-load and load losses due to change in the material have been worked out. Commercial and technical feasibility for adoption of new technology core material has been detailed out and the payback period is quite attractive. By reducing the regular power loss in the transformer, economy of the power sector and global environmental impact can be improved. The paper also covers the working of quantum of electrical power that can be saved if adopted in the state of M.P. The reduced Electrical Power generation requirements due to lower losses have also been translated to reduction in the CO2 emissions polluting the environment.
