Economic considerations of possible overloading the transformer and accepting the reduced life expectancy due to higher hot spot temperature rise must be evaluated carefully against the delay in transformer replacement or addition of a second transformer to increase the capacity. This is a very significant question and quite often asked by the system planner, however, without much success in getting a practical answer. This paper, in two parts will address these interrelated economic issues. Part one deals with the loss evaluation methodology. The second part will deal with the design and economic aspects of transformer overloading, possible loss of life expectancy and the corresponding replacement strategy. The analyses will be done using simple mathematical modeling so that the practicing engineers can make quick. decisive but meaningful decisions.
