Vegetable oils such as Palm Oil (PO) and Coconut oil (CO) are being considered as substitutions to mineral oil in power transformers. Lightning impulse strength is important for insulation design of power transformer and routine test for high voltage power transformer in industries. This paper covers the testing of the lightning impulse breakdown voltages of Coconut Oil (CO) and Palm Oil (PO) relative to Mineral Oil (MO) under quasi-uniform field. Furthermore, understanding the performance of breakdown voltages and electric field distribution in the insulating oil of a transformer during transient is important. Therefore, in this paper, electric field analysis was performed to evaluate the effect of the input voltage condition on electric field distribution. ANSYS software was used for perform electric field calculations based on the finite element methods. |
