摘要
给出了采用过零法和谐波分析法相结合来精确测量金属氧化物避雷器(MOA)阻性电流基波的新算法。仿真运算证明本算法能更准确地测量MOA的阻性电流基波,为MOA性能判别提供了可靠的依据。
A new method be gived to measure MOA′s resistive fundamental harmonic leakage current(RFHC)by over-zero & harmonic analysis methods accurately.The emluator testified that the method can measure MOA′s RFHC more exactly and can make evaluating MOA′s capability more reliable.
