Fiber Bragg Grating temperature / strain sensing system uses Fiber Bragg Grating as a sensitive element. Using the relationship between the center wavelength of Fiber Bragg Grating and temperature / strain, modulation and demodulation is performed using wavelength coding, which can realize physical properties such as temperature, strain, humidity, pressure, displacement, etc.

Whether from the perspective of the power cable`s own safe operation or from the perspective of power system dispatching requirements, the load capacity of the power cable is required to be monitored in real time.When the cable runs under the rated load, the core temperature reaches the allowable value.Once the cable is overloaded, the core temperature will rise sharply, accelerate insulation aging, and even thermal breakdown will occur.Therefore, if the load of the cable can be scheduled and adjusted in real time based on the actual operating ampacity of the cable, not only can it ensure the safety of the cable`s operation and allow its load capacity to be fully utilized, but it can also solve the power dispatch in some cases Power supply problems in medium emergency situations.
