Corona discharge causes a change in temperature on a material surface because of the change in heat coefficient. Visual inspection is the common technique for corona discharge inspection, which costs time and energy. Therefore, developing a remote sensing system is necessary to monitor the phenomenon. This study considers fiber Bragg grating as an optical sensor to sense temperature changes using OptiSystem simulation software. The response spectrum of the reflected signal changes its center wavelength as the simulated temperature changes produce a linear equation of 0.014294 times its temperature change for the initial model, and temperature changes decreasingly by considering heat transfer experiment data. The proposed results show its prospective for further development and implementation.
