电力变压器绕组变形故障的测量分析与判断

采用频响分析法（ＦＲＡ）测量电力变压器绕组的变形故障，具有灵敏度高、试验设备轻便、判断直观的优点。但是，频响分析法也受到诸多因素的影响，要求试验人员具有较高的测量分析能力。本文就测量方法和分析判断的一般原则提出了一些可行的原则，并对电力变压器绕组的变形故障的各种测试方法及其应用前景提出了一些建议。

Analysis and Judgement on Distorted Windings of Power Transformers

Frequency Response Analysis (FRA) is used in measuring distorted windings of power transformers, it is higher in sensitivity, portable in testing instrument and visible in judgement. But FRA is affected by many factors, so the persons using FRA instrument should have high measuring and analysing ability. Some feasible principles on measurement method, analysis and judgement are pointed out. And some advices on measurement of the distorted winding of power transformers and its application prospect are given.
