摘要
由于中性点不接地系统中的电压互感器烧毁的主要原因是铁磁谐振,通过分析铁磁谐振的形成条件、种类和现象,介绍了多种防范铁磁谐振的措施。
As ferroresonance is the main cause of potential transformer burnout in neutral point ungrounded system, various preventive measures against ferroresonance were introduced through analysis of the forming condition, types and phenomenon of ferroresonance.
