摘要
简要分析比较了变压器接地后备保护零序CT安装地点的变化对变压器零序过流保护和变压器间隙零序过流保护的影响,提出了一种相对较优的安装位置。
This paper gives a simple analysis on the influence of different installation site of zero sequence current transformer to transformer zero-sequence over current relay and transformer gap zero-sequence over current relay, and proposed a better installation site.
