摘要：
The internal defects of transformer can be detected by dissolved gas in transformer oil. In this paper, we firstly have the routine test such as DC resistance of transformer, dielectric loss, and so on. Then we do the transformer induction withstand voltage experiment, partial discharge test and make ultrasonic positioning on the discharge single. Finally, we do strip inspection on the transformer and found aging serious problems of outlet device. Through the comprehensive utilization of chemical, materials, electrical test, the accuracy of fault diagnosis of transformer insulation materials and speediness is largely improved.
