The protection for earth fault line selection and fault point location by S injecting current in neutral isolated power system is presented.
介绍了基于“S注入法”的小电流接地系统单相接地故障选线定位保护。
After injecting current into the head of line, the detector can check whether these branches flow current, the fault branch is that the current has flowed.
然后在线路首端注入电流，通过探测器检验几个分支上是否有电流流过，检测到电流的即为故障点所在的分支。
The challenge, however, is extracting the spins to form a spin-polarized current and injecting them into a circuit without the polarization degrading along the way.
唯一的挑战是，如何提取自旋来形成一个自旋极化的电流，然后注入到电路中并保持极化在沿途不发生退化。
