Abstract :
In this paper, a fiber optic based sensor capable of fault detection in power systems is presented. This sensor uses Bragg wavelength shift to measure current in power systems. Magnetic fields generated by currents in power transmission lines cause a strain in magnetostrictive material which is then detected by Fiber Bragg Grating (FBG). Interrogators sense the reflected FBG signals, and the Bragg wavelength shift is calculated. It is shown that the faults in the systems cause a detectable wavelength shift on the Fiber Bragg Grating.
