一起电磁式电压互感器烧毁故障的分析与处理

The burning of an electromagnetic voltage transformer and countermeasures

某变电站发生电压互感器烧毁事故是由于过电压、过电流引起的.采用大容量电磁式电压互感器能够有效消除铁磁谐振过电压,减少事故发生率.

The voltage transformer burned is due to the over voltage, and over current, A large capaci- ty electromagnetic voltage transformer can eliminate ferroresonance troubles and reduce accident rate.
