This paper presents a methodology for optimizing the distribution transformers project, considering the capitalized cost, employing concurrently in your project amorphous core and insulating vegetable oil. The use of amorphous core technology provides a significant reduction of the load losses as the use of the insulating vegetable oil which is a non-toxic fluid and rapidly biodegradable when in contact with the environment, it allows increasing the machine's operating temperature . The use of these two materials have provided considerable percentage improvements in efficiency and cost / power compared to conventional distribution transformers manufactured. The methodology is aimed to create and select designs that have a lower total cost, namely the sum of the transformer manufacturing cost capitalized cost of losses during the useful life envisaged for the equipment. In addition, it presents the case study of a 75 kVA designed distribution transformer and manufactured with amorphous core and insulating vegetable oil, routine employed optimization (developed in VBA Excel), the theoretical results obtained from the optimized design and the experimental results.
