Abstract To calculate current-radial temperature of high voltage overhead transmission line, a radial temperature thermal circuit model in the form of state equation was developed with the thermal equilibrium principle. A calculation method was proposed to estimate the heat flux and heat capacity of conductor on the transmission line radial annular cross section. With linear regression method, the radial thermal resistance of thermal circuit model was obtained by grey box identification. To validate the reliability of model, an experiment was designed to measure the radial temperatures of transmission line with various current. A simulation with thermal circuit model was performed to calculate the radial temperature by Simulink. Comparing the experiment and simulation, the average relative error of proposed thermal circuit model is less than 3.16% in natural convection. The results indicate that the proposed thermal circuit model has potential application applied in radial temperature gradient calculation of transmission line with various current.
