General conclusions are extracted and the difference of zerosequencecurrent distribution from classical theory is found.
最后总结出一般性的结论，其中关于零序电流的分布与经典理论有较大的区别。

The extracted fault characteristics of transient zerosequencecurrent is looked as condition attributes and the multiple of signal enhancement is.
将提取的暂态零序电流故障特征作为条件属性，信号增强倍数作为决策属性，构成一个决策系统。
3
Based on the symmetry component theory, a method of the motor protection is presented by measuring positive, negative and zerosequencecurrent component.
