Theoretical and experimental approaches to noise reduction of current waveform in resin molded voltage-current sensor in power distribution system

The authors have proposed the resin molded type of voltage-current sensor for the real time waveform observation in power distribution systems. The sensor have been designed and implemented based on the FEM, however, it was found that the current waveform contains the remarkable high-frequency noise experimentally. The paper describes the effect of the outer noise on the current sensor waveform theoretically and experimentally.
