| Abstract: | The electromagnetic voltage transformer in the Neutral end grounding system could excite ferromagnetic resonance overvoltage during single phase arcing earthing fault or line energization when no load on busbar or less output lines appeared.Based the analysis of the generation mechanism of single phase arcing earthing fault and ferromagnetic resonance overvoltage,this paper makes the comparison analysis to commom resolutions of clearing resonance and points out some precautions for engineering use. |
