摘　　要：对Rogowski线圈测量原理进行了分析,建立了传递函数模型,在此基础上对Rogowski线圈的电磁参数与其高频传变特性的关系进行了仿真分析,结果表明尽量保证线圈自感一定的条件下,减小内阻、分布电容以及负载电阻,Rogowski线圈的截止频率能达到几百兆赫兹,Rogowski线圈本身的频带宽度能够满足高频行波信号带宽要求,可以用于测量行波.This paper analyses the Rogowski coil for measuring principle and establishs a transfer function model.The paper makes in-depth study about the relationship between Rogowski coil parameters and the characteristic of high frequency transition.The results show that the cut-off frequency of the Rogowski coil can reach hundreds MHz if reducing the resistance and distributed capacitance while keeping a certain self-inductance certain as possible as.Rogowski coils can meet bandwidth requirements of high-frequency traveling wave signal and can measure the traveling wave.
