摘　　要：分析 Rogowski线圈频率特性的结果表明 :测量工频电流时线圈分布参数的影响可忽略 ,线圈的频率特性主要受积分器时间常数的影响 ;测量高频电流时线圈的分布参数对其高频频率特性影响较大 ,且要考虑连接线圈到积分器的同轴电缆、被测电流载体在线圈内的相对位置对其高频特性的影响。实际应用时可把线圈的参数带入到相应的方程得出其高频特性曲线 。According to the principle of Rogowski coil, its frequency characteristics are analyzed. When measuring power frequency current, the effect of distributed parameters can be neglected, the frequency characteristics of the coil are mainly affected by the time constant of integrator. When measuring high frequency current, the effect of distributed parameters can not be neglected; in addition, the effect of the co axial cable connecting the coil to the integrator and the relative position between the coil and the integrator should also be considered. In practice, the high frequency characteristic curve can be draw by putting the parameters of the coil into the corresponding equation, and thus, its high frequency behavior can be analyzed.
