Abstract

The main objective of this research project is to investigate the breakdown voltages of various types of transformer oils commonly used in transformers, including mineral oil, vegetable oil, and palm oil. The breakdown voltage is a critical parameter that determines the ability of the transformer oil to withstand high electric stress levels and prevent electrical breakdowns in transformers. To achieve this objective, a specially designed test cell has been developed, which allows the transformer oil to be filled with a fixed gap distance between the conductors. The test cell will be used to measure the AC breakdown voltage for each type of transformer oil under controlled conditions. The recorded breakdown voltage data will then be analysed to determine the electrical performance of each type of transformer oil. In addition, the Ansys Maxwell software simulator will be utilized to obtain the electric field distribution passing through the transformer oil from the copper sphere conductor. This will provide a more detailed understanding of the electric field behaviour within the transformer oil, which is essential to accurately analyse the breakdown voltage data. Overall, this project aims to gain insights into the performance of different types of transformer oils used in transformers, which can help in the development of more efficient and reliable transformer systems.
