【Abstract】 The accurate measurement of hot-spot temperature of transformer winding can reflect the insulation status, thus it attracts the attention of researchers. The research situation of hot-spot monitoring technique of transformer winding is introduced at first. And then the existing problems of each method are discussed. The application of new technique is especially analyzed in this paper.更多还原
