Analysis and Research of Rogowski Coil Current Sensing Technology

The paper introduces the working principle of Rogowski coil and characteristics of various Rogowski coils, Summing up the productionl principle of high precision coil. The measuring system which is composed of PCB Rogowski coils and integrator are designed by optimizing coil parameters,and the simulation of system is analyzed.The result shows that the system has higher sensitivity and good frequency characteristics, and can meet the requirement of measurement in power system.
