The design, construction and operating condition of grounding equipment affect not only safety operation of powersystem but also electromagnetic interference of substation.
接地装置的设计施工及运行情况的好坏不仅影响电力系统安全运行，也是影响变电站电磁干扰的重要方面。

And the single phase grounding fault location for transmission line should be the emphases in powersystem fault detection.
因此输电线路的单相接地故障点定位应是电力系统故障检测的一个重点。
