摘要:Abstract: Real-time monitoring of temperature along the cable is very important for ensuring the safe oper-ation. Based on the theoretical analysis of Raman back scattering of optical fiber and optical time domain reflection principle, optical fiber distributed temperature measurement system, scheme and software architecture are designed. The system is applied to the online monitoring of power cable, and good results are achieved. It provides a reliable scientific tool for the fault early warning of power cable.
