高阻电路的切换应用包括小电流、高电阻和高阻抗电压应用。
Switching applications of high impedance circuits include low current, high resistance, and high impedance voltage applications.
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.
由于阻抗器的等效电阻为纯电阻，因此在调整电压的过程中不会产生谐波。
Because of the pure resistive nature of the equivalent resistance of impedor, no harmonic will be generated during the voltage regulation.
