Abstract :
In order to solve the problem of self-integrating Rogowski coil failing in measuring High-frequency Traveling wave current accurately, this paper come up with a System Identification solution based on Rogowski coil measuring. Through analyzing the measuring principles of Rogowski coil and using Square wave response to establish the Transfer function of the measurement system, digital correction of Rogowski coil´s low-frequency distortion was finally realized.
