Transformer liquid dielectrics evolved where mineral oil has been the dominant choice until
emergence of synthetic esters and natural esters. Natural ester-based oils have been under …

The remarkable development in high-voltage direct current and high-voltage alternating
current transmission systems calls for a renewed assessment of dielectric liquids for …

Society's increased concern over green house gas emission and the reduced cost of electric
vehicle technologies has increased the number of electric vehicles (EV) and plug-in hybrid …

The use of natural esters as an insulation medium in transformers is well known. This paper
proposes to use Baobab oil (Adansolia digitata) as insulator. The Baobab oil is modified …

Mineral oil (MO) had been in use in transformers for over a century. However, with the ever-
increasing upsurge in voltage and power levels coupled with the depleting reserves of fossil …

Ester based dielectric fluids were found to beat mineral oils in thermal and environmental
aspects. Hence there is a great need of research on ester oils. The present paper is a review …

Desde principios de la década de los noventa se han desarrollado líquidos dieléctricos de
origen vegetal que tienen como principales ventajas las mejoras de los limitantes presentes …

Nowadays researches on the viability of using vegetableor plant-based oils in power
transformers are gaining much attention due to the excellent biodegradability and good …

In this paper, dissolved gasses of natural ester fluid were analyzed to suggest DGA criteria
for transformer filled with natural ester fluid. Samples of mineral oil and natural ester fluid …

In this thesis the use of fuzzy logic techniques for condition assessment and diagnostic
analysis of equipment in electric power systems is discussed. Condition assessment may be …
