In this advance age wherein the latest technology has not only increased the sensitivity of the electrical equipments but also the consumption of electrical power, the distribution network needs to be highly extensive, stable, reliable and efficient. The objective of this paper is to chalk out different strategies/techniques for the rehabilitation of high tension network of LESCO with the help of comparative/combinational computerized study of the system. For the said purpose, a distribution network is selected on the basis of certain planning criteria such as voltage drop, power loss, equipment loading, benefit-cost ratio etc. and different strategies/techniques are chalked out for its rehabilitation thereby leading to a system more stable amicably handling higher energy levels with minimum extra cost involved.
