To maintain the reliability and performance of a transformer, it requires maintenance or even repairs that refer to the condition of the transformer. To find out the condition of the transformer, it is necessary to have electrical testing with reference to the SPLN and IEC standards. With this test, it is hoped that it will be able to detect early damage or irregularities that occur in the transformer and as a reference in taking further action. One form of this electrical test is the temperature rise test, with standards set for the Top Oil temperature of 50 K and 55 K for the average winding temperature. Based on the results of the temperature rise test on the 250 kVA distribution transformer, the results showed that the transformer being tested was in a condition suitable for operation.
