摘　　要：为克服冲击电流测量中常规用分流器存在的问题和不足,介绍了适合于高压冲击电流测量的罗柯夫斯基线圈的设计条件、实用参数及优化措施,并在MATLAB中进行仿真。与圆筒式分流器对比测试表明,罗氏线圈响应频带宽,幅度范围大,8/20μs的7 kA冲击电流的测量误差<1%。In order to overcome the shortcomings of the current divider using in impulse current measurement, the design conditions, utilizable parameters and optimization measures are presented and simulated in MATLAB. Contrast with cylinder current divider, Rogowski coil＇s response is wider and amplitude is extensive with its measurement error〈1%.
