Abstract

This article proposes a new fiber Bragg grating (FBG) sensor for voltage measurement. Based on the theoretical analysis of the relationship between the PZT electrostriction displacement and the applied voltage, using the characteristic of the FBG measurement - the FBG wavelength drift can reflect the FBG radial strain, a FBG voltage sensor is designed and developed. When the DC exciting voltage is in the scope of 0~500 V, processed by the embedded FBG wavelength demodulation system, the wavelength of the FBG will change linearly in the range of 0~34 pm. The test result under the AC exciting voltage is also discussed and the problems need to be paid attention to are analyzed as well
