Enhancing the Performance of Natural High Oleic Ester based Mixed Oil Paper with Nano Insulating Liquid for High Voltage Transformer
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Nowadays insulation paper for high voltage transformer is based on natural ester due to increase in bio degradability and operating life. Recently oil selection based on unsaturated fatty acid content was proposed and this shows better insulation properties compared to normal ester oil. Nowadays nanofluids have the potential to overcome conventional transformer oil by reducing acidity and oxidation process. In this work, olive oil is selected based on low poly unsaturated fatty acid content. Mineral and olive oil is mixed with definite ration and then blended with different proportion of nano particle. This oil is blended with nano particles such as Al₂O₃ and TiO₂. Insulating properties such as degree of polymerization, mass fraction, breakdown voltage, moisture content and acidity are measured as per standards. By comparing the experimental results, Al₂O₃ shows better insulating properties.
