摘要
介绍了利用变电站进出线运行间隔二次电流,通过二次回路调整产生差流来解决校验比相式母线差动保护比相元件的接线正确性的方法。
This paper tests the correctness phase-comparison busbar diffrential protection, It mainly employs the diffrential current control of secondary circuit caused by the running clearance of ingoing and outgoing line in substation to test the line-connection of phase-comarison components.
