Efficiency is always of great concern in the designs of machines. This factor reflects the amount of savings of energy that can be achieved from a particular design. When thinking of long-term uses, evaluation on the applications of higher efficiency machines will result in giving more visible savings of energy. Transformers are examples of such machines that are used extensively to distribute electricity, and in practice, major losses are produced from their cores and windings, these are called core losses and copper losses respectively. / This research is concerned with efficiency improvement of conventional transformers. Attempts have been made by using two configurations of windings that are made switchable. One of these configurations is chosen at one time on the basis of the secondary current. This is based on the theory that, by implementing higher numbers of turns at low load and fewer numbers of turns at high load than conventional transformers have, total losses that are the sum of core loss and winding loss will be less than total losses produced by conventional transformers. / Thesis (MEng(ElectricalEngineering))--University of South Australia, 2001.
