Abstract

This research presents an engineering economic cost evaluation of a 1,000 kVA 3-phase 50 Hz 22 kV-400/230 V distribution transformer. A computer is used to assist in evaluating the cost of the distribution transformer to ensure it is suitable for the load usage, with accuracy, speed, and precision. The evaluation incorporates the transformer loss test results from the factory, interest rates, electricity tariffs, service life, and the environmental cost of energy losses in the transformer. These factors are used to assess and compare the transformer costs to determine the most appropriate option for a project, industrial operation, or business. This allows users to select the most cost-effective and efficient distribution transformer.
