摘要
介绍了低电压短路阻抗法、电容量法以及频率响应法诊断变压器绕组变形的基本原理,并通过一台变压器绕组变形的案例,证明了综合采用三种方法可以提高绕组变形的诊断效率和准确性。
The basic principles of test methods, such as low voltage short circuit impedance, capacitance and frequency response analysis, to diagnose transformer winding deformation are introduced. The combination of three methods can im- prove the winding deformation diagnosis efficiency and accuracy, which has been proved by a case of transformer winding deformation.
