This paper presents studies on economical feasibility of transformers for application on rural areas with low loading. The comparison is based on manufacturing costs and losses capitalization, including different combinations of designs considering materials for cores and windings. A proposition based on conventional designs with high impedance for low-load application is also presented. The proposed high-impedance design presents slight differences in economic and energy gains, compared to standard silicon steel designs, for appli- cations in rural areas. Although their load losses are potentially increased, it is demonstrated that total losses are decreased. Fur- thermore, even considering a higher losses reduction for amorphous transformers, costs analysis indicates that proposed designs can be a more feasible alternative.
