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。
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.
基于上述三相交流电弧炉电路模型，分析了电流不对称和阻抗不对称对电弧功率的影响，并讨论了交流电弧炉三相电参数互相影响的复杂性。
The influences of the asymmetry of current and impedance on the arc voltage and power were analyzed, and the investigation complexity was also discussed.
