Abstract:-The improvement in power scenario will affect the economic development of a country. So it is necessary to give prior importance in power improvement. India is a large populated country and the electricity supply need of this population creates requirement of large transmission and distribution system. Transmission line is an integrated system consisting of conductor subsystem, ground wire subsystem and one subsystem for each category of support structure. Line losses play an important role in its efficiency. Reduction in its losses will improve the power scenario in India. With this view, this paper describes about the reconductoring method and its affect in power system.
1.1. Introduction
Electricity Generation needs to be increased to meet the required demand in India. From the scenario of world electricity generation, it is clear that thermal generation plays huge role in production as compared to other, that is, renewable sources. Other sources include solar, wind, geothermal, combustible renewable and waste and heat.

Fig 1 shows the generation scenario of electricity in India by different source. In recent years availability of power in India has increased and improved but demand has consistently outstripped supply and substantial energy and peak shortages prevailed in 2009-10. In order to meet the deficit between demand and supply, 25000 MW to 35000 MW of power is being produced by diesel generation system. In the past, the selection of an energy resource for electricity generation was dominated by finding the least expensive power generating plant.
In order to improve power generation capacity economically and environmentally, new renewable power plants have to be implemented reducing the dependence on coal, gas and oil. In 2007, the usage of gas and coal is increased as compared to the use in 1973. On the other hand use of oil decreased by a sizable amount during the above mentioned period. Oil usage is reduced from 24.5% in 1973 to 5.6% in 2007.
