摘　　要：针对中性点不接地系统中往往会出现谐振过电压等造成电气损坏,以致大面积停电事故的问题,通过对电压互感器接线中性点处加装一次消谐器的探讨,详述了一次消谐器的作用、种类、使用注意事项等,以有效避免因一次消谐器错误选用而造成的事故扩大。In neutral ungrounded system,resonance overvoltage often causes electrical damage,resulting in large-scale power failure.The installation of a primary harmonic eliminator at the neutral point of voltage transformer is discussed.The functions,types and precautions of the primary harmonic eliminator are introduced in detail,so as to effectively avoid the expansion of accidents caused by the wrong selection of the primary harmonic eliminator.
