“…For that an optical fiber is bonded to a sample, or by thin-film deposition with a magnetostrictive material. The most commonly used magnetostrictive sensing elements were optical fibers coated with nickel [43], metallic glasses such as Metglass 2605S2 or Vitrovac 40-60 [44][45][46][47] [48,49].…”

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.

“…The first experimental evidence of the magnetic field sensing characteristics of optical fibers jacketed with either nickel or metallic glass magnetostrictive materials was reported by Dandrige et al [44]. Both bulk magnetic stretchers, as well as, thin films directly deposited on a single mode fiber (SMF) were analyzed.…”

“…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.…”

“…A range of fiber optic sensors based on a reflective Fabry-Perot (F-P) interferometer (FPI) have been developed in the past two decades for the detection and measurement of a large variety of physical, chemical, and biomedical parameters [4][5][6][7]. Techniques to create the FP cavity have varied from the creation of Bragg gratings in or on the fiber to the use of air-glass interfaces at the fiber ends as the reflectors or using a MEMS diaphragm as the reflect faces.…”
