Use is made of that zero-sequence transformer outputs a voltage signal when phase-failure occurs in three-phase induction motor.
这种新方法的基础是零序变压器在三相异步电动机断相时输出一个电压信号。
At the time of failure, no matter what kind of start state of voltage phase, the zero-sequence transient current has the characteristic of inverse phase.
在故障时刻，无论故障相电压的相位处在何种初始状态下，都有零序电流反向的特征。
It is found that output voltage of zero-sequence transformer is proportional to voltage UA 'a between phase-failure points.
经研究发现，零序变压器输出电压与断相点间电压u _ (A ' A)成正比。
