Study on Fiber Bragg Grating Large Current Sensor

Abstract:

The large power current is sampled by Rogowski coil, then transforms the sampling signals from AC to DC and regulates the signals, the current detection unit is formed with FBG (Fiber Bragg Grating) and GMM (Giant Magnetostrictive Material), the current measurement is achieved based on the F-P interferometer filter demodulation system, finally, linear relationship between the Bragg wavelength shift and external current is validated by experiment.
