摘　　要：提出一种用电流比例标准配合标准电阻的方法来校准工频大电流罗氏线圈,克服了传统标准源校准方法测量工频大电流的量程局限性,解决了工频扩大至20 kA电流量程罗氏线圈的校准问题,并对该方法下典型值的测量结果不确定度进行了分析和评定。This paper proposes a method to calibrate the power frequency high current Rogowski coil by using a current ratio standard and a standard resistor,which overcomes the range limitation of the traditional standard source calibration method to measure the power frequency high current.The calibration problem of Rogowski coil with a power frequency 20 kA current range is solved with the proposed method.The uncertainty evaluation and analysis of the measurement results for the typical value with this method is given in this paper.
