| 摘 要： | 介绍了金属氧化物避雷器(MOA)阻性电流各分量的构成,分析了在线监测时电网谐波对MOA阻性电流各分量的幅值、相位的影响.由于金属氧化物避雷器阻性电流由基波和3次、5次等谐波构成,其中3次、5次谐波的分量占总阻性电流的45%左右,因此在计算阻性电流谐波分量时,应考虑电网谐波的影响才能更精确地计算阻性电流.

| Abstract: | This paper introduces the composition of metal oxide surge arrester(MOA) resistive current,and analyzes the influence of power grid harmonics during monitoring on-line on amplitude value and phase of MOA resistive current components.On account of the fact that MOA resistive current consists of fundamental wave,the third and the fifth harmonics etc and that the third and the fifth harmonic components account for about 45% of the total resistive current,the influence of power grid harmonics should be considered to achieve more accurate results in calculating harmonic components of resistive current. |
