Overvoltages may also BE produced by certain types of asymmetricalfault mainly on systems with ungrounded neutrals.
在中性点不接地系统中,过电压也可能主要由某些类型的不对称故障所引起。

Because the impedance fault location method is easily influenced by the factor such as fault resistance, transformer error and asymmetrical line configuration, the fault location accuracy is lower.
由于阻抗法易受过渡电阻、互感器误差、线路结构不对称等因素的影响,所以测距精度不高。

The fault characteristics of stator winding inter-turn short -circuit and asymmetrical operation of generator are calculated for the fault simulation generator.
