摘要(Abstract)：

在中性点不接地的电网里，带铁芯的电感元件有变压器和互感器。通常认为，这类电网里发生的长时间过电压，多半是由电压互感器与网络零序电容的谐振所引起，为此在电压互感器的开三角绕组配置了“消谐器”以抑制网络中的谐振过电压。事实证明这措施并不十分理想，本文对此进行了分析并提出了看法。
it standed to reason that the long duration overvoltage on the neutral-ungrounded systems werecaused by series reasonances which were introduced by potential transformers and zero equence capacitances.Then the"dampers"were set up at the tertiary windings of potential transformers for damping resonances. Butthe facts show that it was not an effective measure. This paper presents the analysis.
