This paper presents the measured temperature at top oil and on winding at high voltage part, low voltage part due to winding loss. By placing the thermocouples at the bottom, the middle and the top of mineral oil-immersed transformer, the variety winding temperatures are measured. The 3 - test conditions are 1. Short circuit test, 2. Linear load test and 3. Non linear load test. The temperature results show the difference temperature at any parts of the 10 kVA, 380V/220V, 3 phase, Dyn11 and ONAN ventilating transformer. The results of measured temperature will be compared with one another to get the difference temperature. If that temperature is higher than the rated temperature of insulator in transformer, its lifetime will be shorter. Finally, the result will be analysed about the relations among heat at any part and are useful for design, correction and protection of the transformer by heat.
