摘　　要：在小电流接地系统中,经常会发生由电磁式电压互感器饱和引起的铁磁谐振与超低频振荡现象,严重影响着系统的安全运行。本文在分析铁磁谐振产生机理的基础上,根据其类型和特点提出了抑制铁磁谐振的措施。In the low current grounding system, Ferro resonance and ultra- low frequencies caused by the saturation of electromagnetic voltage transformers often occur and endanger the voltage stability and the safety of electric equipments. This paper analyzes the mechanism of the Ferro resonance and puts forward the measures of the restraint of Ferro reso- nance according to its form and features.
