| Abstract: | Based on the analysis of the principle of Rogowski coil,the model of its equivalent circuit was established,and its transfer function was deduced.A new-type precision integrator was designed,and its advantage was proved by using Protel for simulation.The experiment of sensor head based on PCB Rogowski coil shows that the precision reaches 0.5 in grade,which fully satisfies the requirements of design standard. |
