摘要

中性点不接地系统中的电磁式电压互感器

因单相电弧接地故障或合闸充电过程的激发可能引起铁磁谐振过电压。在分析铁磁谐振产生机理的基础上

对常用的消谐措施进行分析比较

并指出使用中应注意的问题。

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.
