Autonomous power supplies of light marking, monitoring, relay protection and emergency control systems of digital high voltage networks are considered, in particular, capacitive power take-offs from high-voltage three-phase power lines with voltage of 110 and 220 kV. Energy is collected in the immediate vicinity of the equipment, ensuring its operation without laying a separate power supply network and with minimal human involvement. The results of the analysis show a rather high technical and economic efficiency of the considered power supply system.
