“…They observed that the frequency response of the coupling coefficient was found to be essentially smooth in a range between 15 and 600 Hz. Hartman et al [55] reported the fabrication and characterization of optical fibers coated with nickel thin-film. The thickest coating was greater than 90 μm and was fabricated by chemical vapor deposition (CVD).…”

Abstract:The intrinsic advantages of optical sensor technology are very appealing for high voltage applications and can become a valuable asset in a new generation of smart grids. In this paper the authors present a review of optical sensors technologies for electrical current metering in high voltage applications. A brief historical overview is given together with a more detailed focus on recent developments. Technologies addressed include all fiber sensors, bulk magneto-optical sensors, piezoelectric transducers, magnetic force sensors and hybrid sensors. The physical principles and main advantages and disadvantages are discussed. Configurations and strategies to overcome common problems, such as interference from external currents and magnetic fields induced linear birefringence and others are discussed. The state-of-the-art is presented including commercial available systems.

“…Compared to the existing methods [8][9][10][11][12][13] that utilize long optical fiber coils, the demonstrated method requires only the fiber length in which the fiber Bragg grating is inscribed, which usually varies from 1mm to 20 mm. The sensor can be designed as a very compact instrument using a matched-filter interrogation system, where a spectrally similar FBG is matched to the sensor FBG by a piezoactuator, instead of the optical spectrum analyzer, since the total wavelength shift that requires to be interrogated is narrow.…”

“…Measurement of magnetic field has been demonstrated with the optical fiber using Faraday effect [8], Lorentzian force [9], and magnetostrictive effects [10], [11], [12] in an interferometric arrangement. Typically, the information encoded as the perturbed polarization state of the light is converted to intensity based data which can then be easily detected using a photodetector.…”

“…Assuming that the affect of temperature is negligible, the spectral dependence of the FBG sensor on the longitudinal strain can be expressed as, where ∆L is the change in length of the fiber, ε z is the axial strain component, p 11 and p 12 are the strain-optic tensors and ν is the Poisson's ratio. For a germania-doped silica fiber, the strain sensitivity of FBG is approximately 1.22pm/µε.…”

Kvantovaya Elektron. (Moscow) 12, 901-944 (May 1985)Optical, fiber-optic, and integrated optical sensors of physical effects are reviewed. The sensors are classified in accordance with their operating principle: amplitude, interference, and polarization sensors are considered. Descriptions are given of the construction of the sensors (or of their sensitive elements) which can react to mechanical quantities (displacement, force, acceleration), acoustic vibrations and pressure, electric and magnetic fields, electric current, temperature, angular velocity, etc. Some of their principal characteristics are described. Important parameters of known sensors are presented in a classified reference table.
