An Overview of Optical Voltage Sensor

摘要

This paper provides a thorough review of optical voltage sensing techniques developed over the last decades. The performances of each technique are compared. The advantages and limitations are summarized. The voltage sensors are catalogued according to the underlying physical principle in order to point out their advantages and limitations. We also present new research results that may be developed into future voltage sensors. Finally, some existing problems and future research directions in this field are indicated.
