This work is devoted to the derivation of an algorithm for calculating the heat resistance of a lightning protection cable, as well as the development of software for the automation of calculations. VL simulation for comparing results with ATP-EMTP. Tasks that were solved during the study: 1. The study of existing methods of calculation, as well as comparing them with the calculation in the program ATP. 2. Derivation of a new calculation algorithm using the method of contour currents. 3. Calculation of simulated overhead lines using developed software and in the ATP program. 4. Comparison of the error of the obtained results in comparison with the ATP-EMTP program. The developed software gives a low percentage of error (from 0.01% to 3.55% in rare cases), compared with the ATP-EMTP program.
