Abstract

In In the electricity transmission system, transformers are utilised to alter voltage levels. As a cooler, insulating oil is required; hence, its longevity is dependent on the insulating oil. The factor of mineral oil is utilized as insulation oil because of its efficient heat transfer, long life and, has good insulating qualities. However, the negative effects of mineral oil on the environment and its slow rate of decomposition should be noted. If there is an oil leak or oil combustion, the present commercial mineral oils that are used as insulation oil can cause contamination of water bodies and the environment such as flora and fauna, air pollution, and soil infertility. Moreover, insulation oils of the organic kind can degrade completely in a short time and have a high breakdown voltage (BDV) strength. As a downside, organic oil has high viscosity and high-cost production. This study focuses on the development of nanofluid-based eco-friendly natural ester oil. The major purpose is to compare the technical performance of the palm-oil-based estertitanium oxide as nanofluid with mineral oil that is commercially accessible and palmbased ester without nanofluid. Using the product of palm oil reacting with alcohol and titanium oxide nanofluid, a simple laboratory technique known as transesterification is used to make a natural ester with nanofluid. The breakdown voltage test will be focused in this project as the main topic for this study is breakdown voltage for nanoparticles added. The sample will go through thermal aging procedure for lengths of 0 hours to evaluate its performance compared with commercially available insulating oil before testing at the industry. The results revealed that by adding nanoparticle, it can enhance the breakdown voltage of the sample oil. The concentration of nanoparticle added also play an important role as different concentration also give different breakdown voltage. For this experiment concentration used was 0.01 g/L, 0.02 g/L, 0.05g/L and 0.10 g/L. From all the concentration 0.05g/L give the best breakdown voltage which is 31.37 kV.
