A Study on Detecting Winding Deformation in Transformers with FRA Method
Author(s): 
Pages: 39-42
Year: Issue:  12
Journal: ELECTRIC POWER

Keyword:  变压器绕组变形频响分析;
Abstract: 介绍频响分析法的基本原理及应用到现场进行变压器绕组变形测试所必须解决的几个关键技术问题;提出不同接线方式变压器进行变形测试的典型试验接线及方法;通过现场实测,明确分接开关档位、信号源位置、变压器套管电容量、变压器出口引线长度等因素对变压器频响曲线的影响,结合 158 台变压器的实测经验,提出频响分析法测试结果的判断原则.
