Externalshunt resistances, such as leaky cables and dirty insulators, may also cause loading errors.
外部的分流电阻，例如：漏电的电缆和肮脏的绝缘子也可能引起负载误差。

Any externalshunt resistance across the voltage source will attenuate the measured voltage, as shown in Figure 2-3.
跨接在电压源上的任何外部分流电阻都会使测量的电压衰减，如图2 - 3所示。

The fault model including the parameters of shunt reactors is established, which is accurately equal to external fault in principle, but hardly applied to current real devices.
