给出了桑迪土壤上发生阶段性高阻抗接地故障时电流谐波的实测值。将测得的低频频谱与变电站连续一周记录的电流谐波进行比较。进行此比较是为了确定120 Hz和180 Hz分量在多大程度上可用于帮助检测高阻抗故障。现场测量的支持一个简单的理论模型和实验室测量。它的结论是，对于所研究的馈线，检测高阻抗电弧故障可能是可能的二次谐波电流的监测。>
The measured values of current harmonics at a staged high-impedance ground fault on sandy soil are presented. The measured low-frequency spectrum is compared with current harmonics recorded continuously for one week at the substation. This comparison was carried out to determine to what extent 120 Hz and 180 Hz components can be used to help detect a high-impedance fault. The field measurements are supported by a simple theoretical model and laboratory measurements. It is concluded that, for the studied feeder, detection of high-impedance arcing faults may be possible by monitoring of the second-harmonic current. >
