Analysis of significant parameters of miscellaneuos insulating fluids with Antioxidants

Transformer have long used mineral oil as an insulant. Mineral oils impact on the environment has been well documented throughout the last century. For such a reason an alternative source of mineral oil is used. Antioxidants are the materials which improve the performance of the vegetable oils in power transformers. Biodegradability, and environmentally friendly in nature are two of the advantages of using vegetable oil. In this work, it is used to select and mix natural fatty acids like sunflower seed oil, Rice bran oil and corn oil in various proportions are used as per the IEC standards. By using IECD standards various critical parameters are determined such as breakdown voltage, Flash point, Fire point and Viscosity.
