Survey of Optical Current Sensor and Optical Voltage Sensor for Electric Power Systems

전력용 광 전류, 전압 센서 연구 동향 조사

In this paper, some of optical current transformers and optical potential transformers for extra high voltage system are introduced. The optical current transformer and optical potential transformer will be adopted in the near future, because of increasing demands of high accuracy and good reliability of current transformer and potential transformer. The application cases of optical current transformers and optical potential transformers are also introduced.
