摘　　要：介绍了一种Rogowski线圈脉冲电流探头时域标定和标定数据处理的方法,将脉冲法时域标定的结果和频域标定结果进行了比较。针对电流探头的低频失真,采用系统辨识方法建立了测量系统的动态模型,并对探头输出信号的失真进行校正。实测数据验证了所建模型的有效性,设计出的数字补偿滤波器可将测量系统校正为一理想的比例环节。A method of time domain calibration and data processing on pulsed current probe which is based on Rogowski coil is introduced. The result of time domain calibration using pulsed signal is compared with the frequency domain calibration result. A dynamic model of measurement system is established through system identification method according to low frequency distortion of the current probe. This method is also used to correct the distorted output signal of the probe. The validity of established model is verified by experimental data and the measurement system can be corrected into an ideal proportional system by designed compensating digital filter.
