Abstract
The application of power systems has been widely used in all walks of life, especially the thermal effect generated by the power system in the application process. Among the many application processing schemes, the detection effect of using the new optical fiber sensor to control or monitor the cable is the most obvious. Although the optical fiber temperature sensor has become mainstream at present, the optical fiber monitoring technology is still not mature in practical application, so it is necessary to conduct in-depth research on the application of optical fiber temperature sensor in the power cable detection system.
