AB The relevance of natural and synthetic esters as insulating liquids for transformer insulation has grown significantly in the last years. Its use has spread in small and medium sized distribution transformers and, although their use for large transformers is still residual, an increasing number of experiences are being reported. On the other hand, commercial natural esters differ in their composition and the accumulated experience with these kinds of fluids is still limited, what hinders the use of this type of insulating liquids as transformer insulation. More experience is needed to increase the confidence of the users and the reliability of the transformers filled with alternative liquids. In this work, a comparative study of the dielectric properties of two natural esters and a mineral oil is carried out. AC and impulse breakdown voltage characterization and dielectric response analysis are included in the paper.
