摘　　要：概述了目前变压器绕组变形测试诊断技术,主要分为离线测试技术和在线测试技术两大类。离线测试技术主要有低压脉冲法、短路阻抗法和频响分析法等。在线测试技术主要有超声波检测法、振动法、基于频率响应法或短路阻抗法测量变压器绕组状态等几种方法。并对上述方法的优缺点进行了比较。The present of detection and diagnosis technique of transformer winding deformation are summarized, which is usually divided into off-line and on-line testing techniques two categories. The off-line techniques mainly include Low Voltage Impulse method （LVI）, Frequency Response Analysis method （FRA） and Short-circuit Reactance method （SCR）. Online techniques mainly include Ultra- sonic method, Vibration method, the method based on Frequency Response Analysis and the method of Short-circuit Reactance Analysis. The merit and demerit of the methods mentioned above were also compared.
