“…Nanopowders are defined as powdered materials with individual particles having sizes fewer than 100 nanometers. The particles present in the nanopowders are very smaller when compared with the wavelength of visible light [9,10]. The smaller size of nanopowders gives them an extremely high surface area to volume ratio that results in extraordinary properties like extreme strength.…”

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.
