Rogowski coil as the special mutual inductor is often applied to measure high amplitude and transient currents in electrical industry. Since there are no iron core, they cannot be driven into saturation. In this paper, the transfer function of the self-integrating Rogowski is proposed based on the analysis of the Rogowski coil. According to the transfer function, bode diagram simulates the effect of changing some of these parameters. Also, the influences of self-inductance, sampling resistance and stray capacitance are disussed in details. Moreover, a high-frequency current transducer for measurement of PD is developed based on the self-integrating Rogowsk,and the actual dynamic response are performed by adopting function generator. Based on the transducer, measurements of PD of needle-plate model under impulse voltage is identical to the results of theory analysis. Finally, the method to obtain an optimum dynamic property in self-integrating Rogowski coil is suggested.
