초록
In this paper, an experiment result on overload of distribution transformer was arranged by top oil temperature depending on capacity and time. This result shows the definition on overload of transformer is different by some factors such as ambient temperature and immediate load. In other words, increased temperature in range of regulation(50K) has time to spare even if the condition of transformer is overload. The algorithm presented in this paper is based on the international standard (IEEE std C57.91), and the safety of switchboard is diagnosed by this aspect mentioned on overload of transformer.
