Abstract: The estimation of losses are essential for obtaining efficiency. The estimation of optimum losses are much important for obtaining maximum efficiency. The conventional design procedure is a trial and error method. Further it is uncertain to obtain optimum values. Here in this study, the design equations are suitably modified such that the objective function and constraint equations are expressed with the help of only 2 variables. Graphical method is explained where the optimum values for both the variables are obtained simultaneously. The values are unique in nature. A single phase transformer is considered and the optimum values for full load losses are obtained and analyzed.
