摘要：

Short circuit impedance test is one of the important methods for the transformer winding distortion diagnose. At present the test current is too low when we using short circuit impedance method. Upon the understanding for electrical properties of the transformer we developed a device with test current up to 10 Ampere, and combined longitudinal comparison method and lateral comparison method as our criterion algorithm. The device we developed matches the requirements of related standards. It comes in a complete set and fits on-site application. Through three practical examples we can see the improvement of the current is effective for the test accuracy in the transformer winding distortion diagnose.
