基于Rogowski线圈的大电流测量

Heavy Current Measurement Based on Rogowski Coil

根据 Rogowski线圈的测量原理 ,从理论上推导了传感器与外接电路所构成系统的传递函数 ,并用 MATL AB对测量系统的幅频与相频特性进行了仿真计算。探讨了灵敏度低的问题 。

This paper analyzes the measuring principle of heavy current based on Rogowski coil. The transfer function of the measuring system is derived, and the magnitude frequency characteristic and phase frequency characteristic are simulated through MATLAB. The paper also discusses the existing problem of low sensitivity, furthermore, a simple and applied solution to this problem using electro integrator is proposed.
