Abstract

The fundamental component iR1 and the third harmonic component iR3 of metal oxide arrester（MOA） leakage current resistive component can reflect the operation state of MOA.Due to the uncertainty of harmonic voltage amplitude and phase

there may be a big misjudgment in measuring total resistive current directly when considering the influence of frequency fluctuation.In the light of inadequacy of the capacitance method

an improved compensation algorithm is proposed in this paper

which can compensate current by use of the relationship between harmonic resistive current amplitude and phase

so that more accurate resistive current under the action of fundamental voltage can be obtained.The results simulated by MATLAB show that the error of iR3computed by the improved algorithm can be greatly reduced

and also verify the effectiveness of this algorithm

so the accuracy of judging MOA operation can be further improved.
