Power distribution transformers have been prevalent in commercial building distribution systems since the inception of modern commercial electricity. Yet as more and more manufactures seek to improve transformer efficiencies by making changes to the design of the transformer itself, a fundamental concept may be overlooked - the impact transformer demand sizing has on power losses. When modern transformers are improperly sized for the application they will be installed for they are not being utilized at their optimum design loading range, which may impact operating efficiency.

This thesis will aim to test and evaluate modern day transformer design coupled with currently adopted energy efficiency standards and their effectiveness in conjunction with code required sizing restrictions. The evaluation will collect general transformer loading percentage data from commercial power, higher education campuses, as well as specific transformer operating characteristics from actual installed transformers. This information will be further investigated to determine how various load size and type alter the system efficiency and loaded power losses. The computer program Pspice will be used for modeling and simulated calculations while applicable energy and safety codes will be the references for transformer specifications and operating characteristics.
