		abstract={There are many disturbances in electricity or many problems during the distribution of electricity, one of the most common failures or problems encountered during the distribution of electricity is regarding the transformer, because the transformeroperates continuously. The problem with the transformer occurs because of the failure of the transformer oil insulation caused by a decrease in the breakdown voltage value. Insulation failure can occur due to several factors including aging of the insulation, decreased dielectric strength, and overvoltages affecting the insulation. By testing the breakdown voltage, it is expected to be a reference material to maintain the performanceor life of the transformer. Testing using the Megger OTS80PB Breakdown Voltage Test Equipment. The feasibility of transformer oil uses breakdown voltage testing as a result of feasibility simulations based on international standards to increase reliability in powertransformer maintenance in the industrial world, especially for public services. With a higher breakdown voltage, it proves that the oil is still suitable for use. In this study, the average breakdown voltage on the main tank top was 80.3kV/2.5mm, the main tank bottom was 80.3kV/2.5mm and the tap changer was 79.8kV/mm which was in accordance with the PLN (SPLN) 49-1/1982 must have a breakdown voltage of >40kV/2.5mm.}
