Temperature calculation of power cable conductor in real time

The node voltage method is widely used to solve electric circuit problems. It is also an effective method to set up and calculate power cable thermal conditions because the equivalent thermal circuit of a power cable is mathematically similar to an electric circuit. According to real time measurement results of polymeric jacket temperatures of power cables, the temperature of the cable conductor may be calculated using the node voltage method. Furthermore, the power cable load current can be controlled in real time based upon the conductor temperature
