| Abstract: | The basic structure and working principle of an optical current transducer based on Rogowski coils are introduced. Simulation is carried out using transfer function method with established circuit model under Simulink environment. Its transduction characteristics are analyzed under normal and faulty conditions of electric power system. Simulation results show that,it follows the waveform of primary signal and reflects the frequency component change of original signal,with wider bandwidth and better transient performance. |
