Voltage Sensor using Fiberoptic Fabry-Perot Interferometry
초록
A noble fiberoptic voltage sensor system utilizing an interferometric transducer has been introduced for high voltage measurement. The sensor system employs a fiberoptic Fabry-Perot interferometric strain sensor to convert voltage to displacement in an auxiliary movable electrode. The operating mechanism is based on the fact that the electrostatic force acting on the electrode system by the applied voltage results in strain variation on the Fabry-Perot interferometry. The experiment results show that the proposed voltage sensor has the potential to be extended to very high voltage system with appropriate auxiliary electrodes.
