Abstract :
A Rogowski coil in a conducting shield can be considered as a slow-wave transmission line. By carefully constructing the slow-wave structure in such 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 (≅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. Details of the experimental results for the effects of the terminating resistance on the probe response are also presented. These results agree with theoretical predictions
