Besides there is also some alternatives such as an inductance conversion using differential transformer and space curve deformeter and variable resistance pressure transmitter.
除此之外还有利用差动变压器和扰曲线应变计的电感变换方式，以及变电阻式压力变送器。

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 factors that cause the resistance unbalance of transformer winding are summarized and analysed.
