Abstract On-line monitoring the varistor column could reflect the real performance of arresters in service. The interphase interference affects the leakage current much due to the short distance among three phase arresters. Therefore, a new method based on resistance-capacitance network model for on-line monitoring of high voltage ZnO arresters is put forward. Herein, iterative algorithm is adopted. Thus, the interphase interference of monitoring arresters can be eliminated effectively. Firstly, the leakage currents and phase angle differences are acquired by measuring the 500kV arresters and 220 kV arresters in a substation. Then, the partial capacitances through finite element method are obtained. Finally, the varistor column resistance of each section per phase is calculated. The calculated results agree well with the measured results, which demonstrates the effectiveness and correctness of the proposed method.

Key words： High voltage arresters resistance-capacitance network interphase interference valve resistance resistive current finite element method
