【Abstract】 To inerease the number of passes of light around the active conductor is themain methods to incerease sensitivity of Faraday effect optical current transducers(OCTs). In this paper, a dual-ring and a multiple-ring optical path structure of OCTsensing probe is designed and the experimental results of the dual-ring structure are pre-sented.更多还原
