description: The masters thesis is devoted to the development of a multi-tubular arrester for the protection of 10-110 kV overhead power lines from direct lightning strikes, effi-ciency assessment and determination of the arrester test program for various voltage classes. As a result of this work, an analysis of scientific articles and literature on the stated topic, as well as an analysis of existing means and methods for protecting over-head power transmission lines and substations were performed. A design of a tubular arrester was developed and research tests were carried out. Arrester test programs were determined based on mathematical modeling methods using the ATP-EMTP software and empirical calculations taking into account the assessment of the line protection efficiency. The possibility of modeling lightning current pulses on a 300K GIN with an amplitude, duration and steepness in accordance with the adopted test programs was confirmed. POM-C (Polyoxymethylene) and F-4 (PTFE) gas-generating materi-als were used in the arrester design, which ensured a significant improvement in arc quenching and confirmed the potential for using similar materials. An analysis was carried out indicating the advantages and disadvantages of the used means for record-ing high currents. All studies and experiments were carried out using the areas and equipment of Peter the Great St. Petersburg Polytechnic University and JSC Â«NPO Â«STREAMERÂ».
