154㎸ 전력용 변압기 부하별 온도특성

This paper describes temperature characteristics with load for 154kV power transformer. We insert the optical fiber sensors in order to measure the temperature depending on the position. We analyze the temperature distribution when load of 154㎸ power transformer is changed from 30% to 120%, As the results, temperatures is measured from 36.3℃ up to 125.2℃ at the top of high voltage winding and is measured from 32.4℃ up to 103.3℃ at the top of low voltage winding. The temperature of low voltage winding is the most highest than other location of winding for 154kV power transformer.
