Hanvy - Power Cable Ampacity Monitoring System
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.
The distributed optical fiber temperature sensing system is used to monitor the cable surface temperature in real time, and calculate the cable conductor according to the cable type, cable laying method, cable losses, thermal resistance and external thermal resistance of each part of the cable body, and specific weather information.
