description: The topic of the final masters qualification work: "Research of lightning protection of a double-chain 330 kV overhead line without a lightning cable when using protective devices.". In this paper, various methods of lightning protection of a section of a 330 kV doubleâchain overhead line "Vladikavkaz - Nalchik" without a lightning cable are investigated. The nature of lightning overvoltages was considered and a theoretical calculation of the number of line outages per year was carried out. An experimental model of a 330 kV overhead line has been created in the EMTP-RV software environment and emergency operating modes of the line have been simulated when lightning hits a support or wire. Experimental values of the curve of dangerous currents and energies released on protective devices during lightning overvoltages were also obtained. With the data obtained from the experiments, calculations were made of the probability of occurrence of dangerous energies for protection devices and the number of failures of the devices at certain values of the lightning charge. The author of the work analyzed the operation of 330kV protective devices of the RVL and OPN type.
