Design of digital integration in Rogowski coil current measurement system

介绍了外积分Rogowski线圈的数字积分方法,分析了模拟和数字两种积分器各自的性能,用MATLAB软件对以上各参数进行了仿真计算,设计了用于工频暂态大电流测量的数字式Rogowski线圈测量系统,并在暂态电流下进行了试验,结果表明用数字积分方法比模拟积分方法更好.

in this paper, the digital integration methods of the integral Rogowski coil are introduced, and the performance of both analog and digital integrator are analyzed, then the above parameters are simulated by using MATLAB software. The digital measurement system of Rogowski coil is designed for the heavy-frequency transient current measurement and tested under transient current. The results showed that the digital integration method is better than analog integration method.
