Abstract

Power transformer is a very important and costly part of the electrical generation, transmission and distribution system network. Transformers depend on the high dielectric strength and cooling properties of insulating oil to maintain normal operation. Statistically, most of the transformer damages occur due to the dielectric insulation problems. The dielectric insulation problems were affected by several factors, such as water content, suspended particles, gas bubble, acidity and pressure. For example, the dielectric strength of dry oil can be decreased due to the presence of water in the oil. Hence, it is important to improve the insulating characteristics of transformer oil. Recently, dispersing nanoparticles in the oil has developed transformer oil-based nanofluids. It has been shown that some of these nanofluids have much greater dielectric breakdown strength or thermal conductivities than the host transformer oil. Nanoparticles have affected changes in electrical properties when dispersed in insulating oil. Thus, this project aims to prepare nanofluids using palm fatty acid ester (PFAE) oil by dispersing it with iron oxide (Fe3O4); conducting nanoparticles. Then, a setup of high voltage apparatus for breakdown voltage test according to IEC 156 standard will be prepared. Next, the nanofluids will be tested to determine its AC breakdown voltage under moisture influence. PFAE oil as a base oil is compared with the percentage of water presence in the Fe3O4 nanofluids. This project expected to give benefit to electrical generation, transmission and distribution system network by improving the AC breakdown voltage of transformer oil-based nanofluids. This is because nanoparticles dispersed in insulating oil are promising to enhance the AC breakdown voltage.
