Abstract :
An FBG and GMM based optical fiber electrical current sensor for engineering application was developed. GMM exposure to AC current induced magnetic field to cause elongation of GMM and FBG and wavelength drifting of FBG. CWDM device was used for demodulation. Transfer function and frequency of the sensor were reported.
