摘　　要：在中性点不接地的电力系统中,PT谐振是出现最为频繁和造成事故最多的一种内因过电压现象,严重影响配电网的安全运行。文章简要分析PT谐振过电压产生的机理,并对几种消谐措施的效果进行比较与分析。In non-ground neutral power system,Ferromagnetic PT resonance is a kind phenomenon of the most frequent and causing the most accidents in internal overvoltage, seriously affecting the safe operation of distribution network. This paper briefly analyzes the mechanism of resonance overvoltage,also analyzes and compares the effects of several measures to eliminate resonnance
