电压互感器铁磁谐振及优化4VT的消谐措施

Countermeasures about the Ferroresonance of Voltage Transformer and the Resonance Elimination Measures by Way of Optimizing 4 VTs

通过对常用的几种消谐方式的工作原理及消谐效果分析,得出结论,开口角打开的4VT消谐方式是较优的一种消谐措施。

By means of analyzing theories and effects of the usual different resonance elimination measures,we conclude that 4VTs of opening angular aperture is a better way for resonance elimination measures.
