A survey on natural esters based insulating fluid medium for transformer applications

Insulating fluid priorities as an imperative part for the being expectancy of the electrical device such as transformer. A product of gasoline fuel like mineral oil has turned out to be overwhelming insulating fluid of t transformer for over several decades for its sublime cooling as well as dielectric properties. In any case, utilization of gasoline fuel like mineral oil, obtained as of a non-sustainable power basis, has impacted nature of its non-biodegradability characteristics. As a result, many authors guide their preference and priority for renewable and biodegradable choices. The various vegetable based natural fuel like Coconut oil, sunflower oil, rice bran oil, corn oil, soybean oil and so forth are well thought-out as contrasting options toward supplant mineral oil as insulating fluid of the electrical device such as transformer. This paper accords a latitudinous survey of various insulating fluid utilized in a transformer. The various research findings by the author has been inferred towards the superior quality renewable and biodegradable insulating fluid. Finally the qualities of natural esters (vegetable oil) to overcome the drawback of existing fluid is commented. (c) 2021 Elsevier Ltd. All rights reserved.
