| 摘 要： | 采用阻性电流中的基波分量ir和三次分量i3r作为金属氧化锌避雷器(MOA)的监测信号可以及时地发现其老化或劣化现象。但是电网谐波电压将会影响ir、i3r监测的准确性，该文就这种影响进行了详细的仿真研究；并提出了改进的容性电流补偿法，用以求取电网谐波电压情况下的阻性电流。

| Abstract: | It is reasonable to adopt the resistive leakage current's basic component and third component as Metal Oxide Surge Arrester's indictors. This indictors can find aging phenomenon of Metal Oxide Surge Arrester timely. But the existence of harmonic voltages in the power system will have influence on the indictor's accuracy. This article will analyze this effect and put forward an improved compensation method to separate the resistive leakage current under the existence of harmonic voltage. |
