电流回路接线故障时电流测量值的推演

摘要

This paper expounds the different current circuit wiring fault cases affect current measurement.The same error and phase sequence errors, the single-phase earth fault cases comparison and analysis of the influence of the current measured value.This can be improved in practical application in the circuit measuring current numerical abnormalities, precise positioning and finding the cause of line failure quickly.%阐述了在不同的电流回路接线故障情况下对电流测量输出值的影响.分别就同名端错误、相序错误、单相接地故障情况下对电流测量值的影响进行的对比分析.在此方面的研究所得可以提高在实际应用中线路测量电流数值出现异常时,对故障原因的精准定位与查找,并高效排除线路故障.
