A device for calibrating Rogowski coils in time domain.
In this article a device for calibrating Rogowski coils in time domain is designed, which can obtain the sensitivity and dynamic response of the Rogowski coil by means of measuring currents of long pulse durations and few nanoseconds rise time. Its key device is a current step wave generator, which can generate the output with rise time of <3 ns and with duration time of >300 ns.
