A Rogowski coil in a conducting shield can be considered as a slow-wave transmission line. By carefully constructing the slow-wave structure in a way that the distributed capacitance becomes large (on the order of nF) and the coil inductance is at least several microhenries, it is possible to obtain a high-sensitivity (a 1 V/A) Rogowski coil for a pulse duration of up to several microseconds. The design and performance of such a slow-wave Rogowski coil are described in this paper. Details of the experimental results for the effects of the terminating resistance on the probe responses are also presented. These results agree with theoretical predictions.
