摘要
介绍了电磁式电压互感器在不接地系统中,发生谐振的原因及防止措施,如减少同系统中的电压互感器(TV)的台数,提高TV的饱和情况,在TV中性点处装设消谐器等。实践表明,采取措施后的效果明显。
The cause and precautionary measures of resonance occurred m electromagnetic voltage transformer m ungrounded system were introduced, such as decreasing the number of voltage transformer （VT） m the same system and raising the saturation of TV, as well as installing resonance absorber m TV neutral point etc.. The practice shows that the effect with these measures is obvious.
