| Abstract: | The reasons for temperature increment during power cable running are analyzed,and the principles of temperature measurement based on Bragg grating,Raman scattering and Brillouin scattering in optical fiber are introduced briefly.According to the status quo of power cable temperature monitoring,the application modes of three types of optical fiber sensors for monitoring power cable are discussed in detail.Based on the comparison of characteristics and performances of the three sensors,the submarine cable line monitoring case based on Brillouin sensing is introduced.With the development of smart grid,optical fiber sensors,especially the sensors based on Brillouin scattering will play important roles in the power cable monitoring in the future. |
