Temperature reduction analysis of solid insulating materials dipped in natural ester plus inorganic oils

Abstract

Transformer insulation is greatly aided by the use of natural ester-based insulating oils. Because of its essential characteristics, ester-based insulating oil satisfies the requirements for fluid transformer dielectrics. From the past century, transformers have used paraffin oil as both an insulating fluid and a temperature distribution agent, because it is lower bioactivity, it harms the environment and the azure. Additionally, non-renewable hydrocarbons are scarcely available. However, lipids are crucial to the fundamental properties of fluid dielectrics made from vegetable oils. As a result, Unsaturated Fatty Acid Ester (UFEO), and High Saturated Fatty Acid Ester Oil (SFEO) are used as two different types of oil samples. Oil swatches crucial characteristics are initially obtained in accordance with the recognized. All of the oil samples were then subjected to an accelerated thermal aging study to determine their thermal stability. Then, using a dissolved gas analyser, combustible gas estimation of oil samples was done. Results demonstrate that crucial SFEO characteristics are comparable to those of other products. Additionally, insulating material degrades much more slowly in SFEO than it does in other oil samples. Finally, SFEO emits a less-combustible gas made of paraffin oil and enhancer.
