变压器铁心多点接地故障定位的初步探讨
摘要
为对变压器铁心发生的多点接地故障进行准确定位提出了高频法和行波法两种检测方法
并对它们进行了较为详细的分析和比较。同时
对实用前景较好的行波法进行了详细实验验证。
Abstract
To solve the problem of locating the multipoint earthing of the transformer core
two novel methods
named as high-frequency method and travelling-wave method
are analyzed and compared in detail.Meanwhile
experiments are carried out to verify that the travelling-wave method has a good agreement with the theoretical analysis.
