apparent impedance meaning in Chinese

表观阻抗
视阻抗

But due to the existence of the fault resistance , the branch current , the zero sequence mutual coupling and so on , the apparent impedances and protection scope of distance protection will change , thereby affecting the performance of distance protection and the safety operation of power system
然而，由于过渡电阻、分支电流和零序互感等因素的影响，会改变距离保护测量阻抗的大小，造成距离保护动作范围的扩大与缩小，从而影响距离保护的性能，威胁电力系统的安全运行。
