    Abstract: The paper expounded the working principle of arc extinguishing device. Introduction was made to three kinds of compensation modes of arc extinguishing device and their influence on running condition of power grid. Taking a case of abnormal system voltage caused by the arc extinguishing device and capacitance series resonance of power grid for example, this paper gave the analysis and diagnosis methods of arc extinguishing device series resonance case and analyzed the reason of abnormal system voltage, raising some improved suggestions to avoid
the similar faults of abnormal system voltage happening again.
    Key words: arc extinguishing device; resonant; abnormal voltage
