The paper research theeffect of three-phase unbalance by unbalance of earthed capacitor, Analyze how toeffect fault selection and propose a method to resolve this problem.
本文针对由对地电容不对称引起的三相不平衡电流进行理论推导,以能量法为例具体分析了对选线影响的,并且借助有效域的思想提出了具体的解决办法;另一方面针对小电流接地系统中的没有很好解决的问题―瞬时接地故障,提出了一种新的暂态选线算法,其主要思路是进行相关分析,但是在相关分析之前做了两个处理,一是把线路的电流进行处理,二是对处理后的电流用形态学的方法进行滤波。

补充资料：三相
【三相】
（名数）一、解脱相，言无生死之相也。二、离相，言无涅槃之相也。三、灭相，言生死涅槃之无相，其无相亦无。即非有非无之中道也。法华经药草喻品曰：“如来说法，一相一味，所谓解脱相离相灭相。”文句七上曰：“解脱相者，无生死相，离相者，无涅槃相，灭相者无相，亦无相。”又曰：三有为相。(参见：有)
