摘要
提出了一种校正自积分式Rogowski线圈波形畸变方法,该方法通过构建校正电路对Rogowski线圈忽略的电阻压降项进行补偿来实现.实验结果证实了该电路能够很好地校正波形的畸变.分析了校正后Rogowski线圈的幅频特性,结果表明:Rogowski线圈经所设计的校正电路后,上限频率保持不变,而下限频率延伸到零.
A project was proposed to correct the distortion of waveform. In this project, a correcting circuit was designed to compensate the ignored voltage generated by the parasitical resistor and sampling resistor. Experiment result has shown that this project is practical and effective. At the same time, the amplitude-frequency response characteristics of corrected Rogowski coil were analyzed, and the result has shown that the range of the corrected Rogowski coil is greatly extended to low frequency.
