Application Research on High Voltage Switch Cabinet Based on Fiber Bragg Gratings Temperature Measurement System

As a temperature sensor, the fiber gratings get a rapid development with its own advantages. We have done some experiments to test the temperature response characteristic of the optical fiber grating Based on introduce the principle and the structure of the optical fiber grating temperature detection system, and the experiments verified a better fitting relationship between the optical fiber grating reflection peak wavelength and the temperature, showed that the measurement error of the system is small, and the system works reliably.
