Overhead power line inspection using a prediction model based on system analysis Surveillance of Temperature Using a Modeled Optical System

Modulation of an optical fiber’s index of refraction at regular intervals is known as “Fiber Bragg Grating.”. It operates on the basis that a rise in temperature above the reference point causes a change in the wavelength of the light source, and vice versa. In this study, we discuss the design and analysis of a Fiber Bragg Grating Sensor for tracking and measuring powerline temperatures across a certain temperature range. The highest reflectance of the Bragg wavelength was calculated by Optisystem simulation. The FBG interrogator claims that temperature changes are associated with shifts in the reflected light spectrum.
