For temperature measurement under the environment of high voltage and strong magnetic interferences

we proposed a solution based on optical fiber temperature sensor.We designed a new optical fiber temperature sensor

which significantly improved the accuracy and stability of temperature measurement by utilizing double wavelength light source and designed compensation loop.Mathematical simulation and experiment verify the high accuracy of the optical fiber temperature sensor.Moreover

the optical fiber temperature sensor has good insulation as well as excellent anti magnetic interference property with small volume

easy installation and lower cost.
