| Abstract: | The technique of distributed temperature sensing(DTS) has found use in electric cables,which allows accurate calculation of the conductor temperature in power cables in operation and understanding of the real-time ampacity of the cable.We established a method for calculation of the conductor temperature from the sheath temperature by using a mathematic model of concentrated parameters and made discussions on the factors affecting the accuracy of the calculation.Finally,we introduced the application of a sof... |
