The Development for a Applied Electronic Current Transducer

Direct against insufficient of analog integrator, this paper has put forward a kind of practical improvement analog integrator, which can reduce drift of the integrator, and restrain low frequency noise. And manufactures an electronic current transducer which composed of Rogowski coil and analog integrator. By the view of experimental result, the whole system has the higher precision of measurement and the ability to measure the instantaneous response of current.
