This research presents an analysis of the design of transformers used in distribution systems to minimize material costs, achieve acceptable loss values, and comply with regulations. The research process involves designing the transformer while considering loss values and comparing the costs of key materials. The study focuses on transformer sizes commonly used in the industrial sector and installed in the distribution systems of the Provincial Electricity Authority (PEA). The selected transformer 3 Phase 50 Hz 22000-416/240 V Dyn11 sizes are 250 kVA and 500 kVA, in accordance with the new regulations announced by the electricity authority. The results from the design analysis can serve as guidelines for improving transformer designs to reduce costs, increase efficiency, and ensure that loss values meet regulatory requirements. Additionally, it provides a good basis for decision-making when selecting transformers with low loss values.
