The subject of the graduate qualification work is « Technologies providing supply of secondary circuits of overhead line towers in remote areas». The work is devoted to the analysis of existing systems of autonomous power supply for warning lights on high-voltage transmission lines. The main part presents an alternative hybrid design that combines solar panels with an electromagnetic field harvester to ensure continuous, reliable operation in remote locations without grid access. This final qualifying work describes the limitations of single-source power systems (solar-only or battery-only) for safety-critical applications, particularly their inability to maintain continuous operation during prolonged periods of low solar radiation, such as winter conditions in Nizhny Novgorod, Russia. For this reason, a hybrid system was modeled, and the performance of the proposed equipment was evaluated under various solar radiation levels.
