Power transformer is a device used to increase or decrease the voltage in the distribution of electric power. Insulation resistance itself is a resistance contained between two wires that are insulated from one another or resistance between one channel wire with the ground. The test is usually in the form of insulation resistance testing using the polarity index method where the transformer will be tested to determine whether the transformer is in good condition or not. The purpose of delta tangent calculation is to measure capacitive leakage current in the transformer. Furthermore, oil testing by testing the breakdown voltage on oil, is carried out with a six-time measurement and is made on average to be compared with a predetermined standard. From the calculation of the polarity index, it is obtained that the overall support test results are above 1.25 and above 2, it means that the polarity index values for insulation prisoners can be said to be still good. The test results for tengen delta show overall results below 0.5% and that means the delta tangent value shows a good number. The results of the test for the breakdown voltage of insulating oil for upper oil, lower oil, OLTC oil show an average of 87.4 kV / 2.5mm, 88.1 kV / 2.5mm, 39.1 kV / 2.5mm are still in good condition.
