Aplicação do Óleo Vegetal de Andiroba (Carapa Guianensis) como Fluido Isolante Dielétrico em Transformadores de Distribuição de Energia

Abstract

The energy industry faces operational, technological, economic, and environmental challenges, requiring sustainable and efficient solutions. This study aims to verify the technical feasibility of applying andiroba vegetable oil (Carapa guianensis) as a dielectric insulating fluid in power distribution transformers. The physicochemical and dielectric properties of andiroba oil were analyzed and compared with commercial vegetable insulating fluids and mineral oil. The results indicate that andiroba oil has characteristics within the limits established by the ABNT NBR 15.422 standard, although specific treatments are needed to meet other specifications. It is concluded that andiroba oil is a viable and sustainable alternative to replace mineral oil in transformers, contributing to the economic and environmental development of the Amazon region.
