In the newfangled world, electrical energy is the most important thing, and we cannot live without it. The recent research has predominated that petroleum by-products are available only for a few hundred years. This paper is especially clear to meet out that. After some years, the mineral oil in the transformer needs to be changed due to its degradation of insulation. The mineral oil used in the transformer acts as insulation as well as cooling purpose. The used mineral oil can be recycled by adding some additives for reuse purpose. In this paper, the oil chosen is neem oil, sunflower oil and mahua oil and it is treated with antioxidants and nano powders. "Breakdown voltage, flash point, fire point, acidity, and viscosity are measured in consonance with standards". To reduce the oxidation stability natural and synthetic antioxidants are preferred, and Nano powders are also used for improving the properties of the oil. Synthetic antioxidants such as Beta Carotene and TBHQ and selenium are preferred as natural antioxidants. Selenium is used. Before and after the addition of antioxidants and nano powders the measurements were done. By doing this analysis, the transformer oil is used for reuse purpose and it has a longer lifetime. After antioxidants and Nano powders are added, the property of the transformer oil is increased.

“…Research works had proven that the vegetable oils with mono unsaturated fatty acids are more useful for high voltage applications [6]. The vegetable oils meet the environmental concern and dielectric requirement, but it has poor biodegradability [2,[7][8][9]. The addition of antioxidants reduced the oxidation and didn't change the dielectric properties [10,11].…”

Present growing demand for renewable, environment friendly and biodegradable insulating liquids for high voltage applications lead to find the potential alternative to petroleum based mineral oil as insulating medium. In this paper, an attempt is made to find the alternative insulating fluid with better insulating characteristics and eco friendly nature. This work reports on the experimental investigations on the edible natural esters and their blended combinations. The investigations are carried out for finding the critical properties such as breakdown voltage, flash point, fire point and viscosity according to international standards. Olive oil, rice bran oil and soya bean oil based edible natural esters are taken for investigations in individual form and in blended combinations of them. Blended combinations are taken in the range from 0% to 100%. From the experiments, it is found that the edible natural esters have the potential to replace the traditional mineral oil. The edible natural esters and the blended combinations of the edible natural esters have the better properties than the mineral oil. Their eco friendly nature, biodegradability and better insulating properties of edible natural esters pave the way for new insulating medium for high voltage applications.
