Abstract: The measure sensor, Rogowski coil is the key part of the electrooptical type current transformer. According to the analysis of the design principle and the equivalent circuit of the Rogowski coil, the measure relation was educed, the pretreatment to the Rogowski coil’s sampling signal was done, and the frequency characteristic to the treatment circuit was analyzed. Experiment data of the disposal circuit and Rogowski coil show that there is the good linear relation between the measured current and the output voltage, and the Rogowski coil has enough bandwidth.
Key words: Rogowski coil; electrooptical type current transformer; frequency character
