Investigating the Critical properties of High Oleic Natural Esters with Nano-Composites

Introduction

For over one-hundred years, petroleum-based mineral oils have been used in liquid-filled transformers for insulation. The popularity of mineral transformer oil is due to availability and low cost, as well as being an excellent dielectric and cooling medium. The application of mineral oil in power system equipment like transformer is potentially hazardous to environment. The exploitation of petroleum oil is running out of demand and in the near future, oil scarcity exists. India is a tropical country, which produces vegetable oils like coconut oil, palm oil, pongamia pinnata oil, olive oil profusely and it can be used as dielectric fluids in transformer. To be more proficient in the operation of transformer, these vegetable oils should be converted into superior dielectric
fluids. With the development of new insulation materials, vegetable oil, the best substitute for mineral oil has gradually been widely used in the liquid insulation of transformers. In liquid-filled transformers, the insulating liquid plays two important functions by providing the electrical insulation (in combination with a solid such as cellulose) and removing the heat generated by the windings. This project is proposed to analyze the performance of natural ester with antioxidants.

We can find suitable oil for improving the critical parameters of insulating fluid. Moreover, vegetable oil could be an appropriated response to environmental, safety and health problems, and could reduce the exploitation and end-life costs of transformers. Based on the test results obtained, an economic solution is obtained and a recommendation is imparted to replace mineral oil with vegetable oil. The interpolation functions are calculated based on the results obtained in minimum and maximum concentration of antioxidant added.

Achievements

High Oleic Natural Esters with Nano-Composites could be an appropriate response to environmental, safety and health problems, and could reduce the exploitation and end-life costs of transformers. Based on the test results obtained, an economic solution has been obtained and a recommendation is imparted to replace transformer oil with high Oleic oil with Nano-Composites. Dielectric properties of vegetable oils, mineral oil was investigated and compared. The property of vegetable oil was investigated against standards, and the results shows that the vegetable oil has a very good potential to be used as a dielectric fluid. The added advantages of vegetable oils in electrical equipment are that they have good biodegradability, which is well suited to vegetable oil as an organic natural ester. Hence the development and usage of dielectric fluid from vegetable oil base could ensure compliant to environmental and safety laws.
