摘要
通过案例证明判断变压器绕组变形的三种方法,即电容量法、频率响应法、低电压短路阻抗法,将这三种方法结合起来能行之有效地正确判断出变压器绕组是否发生变形,可以最大限度地避免误判断。
It proves three methods of judging transformer winding deformation through case studies,namely capacitance method,frequency response method and low voltage short circuit impedance method.Combining these three methods can effectively and correctly judge whether transformer winding is deformed or not,and can avoid misjudgment to the greatest extent.
