浅谈三比值法在变压器故障诊断中的应用

Elementary Introduction to Use of Three-Ratio Method in Diagnosis of Transformer Failures

结合两个具体实例阐述了三比值法在变压器实际故障判断中的运用。实践证明,三比值法是非常适用的一种变压器故障诊断方法,但在具体运用时还必须充分考虑其它因素进行综合判断分析,才能够较准确地找到故障根源。

In connection with two concrete examples the use of the three-ratio method is elaborated in the diagnosis of actual failures of the transformer. Practice proves that the three ratio method is a very suitable method for the diagnosis of failures of the transformer, but in practical application other factors are to be taken into full consideration for comprehensive judgment and anlysis, so as to be able to accurately find out the sources of failures.
