摘要:
An optical fiber for a temperature sensor and a power device monitoring system that can measure temperatures at different measurement positions by a simple construction are provided. An optical fiber for the sensor 10 comprises a temperature assurance FBG 20 and temperature measurement FBGs 30 as FBGs wherein the refractive index of a core changes periodically. Wavelength band of light incident to the optical fiber for the sensor 10 includes Bragg wavelengths of the temperature assurance FBG 20 and the temperature measurement FBGs 30. The power device monitoring system 1 measures temperatures of the temperature assurance FBG 20 and the temperature measurement FBGs 30 based on their Bragg wavelengths.
