Abstract
Increasing efficiency of power transmission lines is an important factor for providing agricultural objects with electric power. During the development power transmission systems, lines direct current, lines alternating voltage of industrial frequency and lines of alternating voltage high frequency have appeared. The author considers some features of operation power transmission systems over single-wire transmission lines operating at high frequency in range of 5-20 kHz. The system allows to transmit electrical energy on one wire with return through low-conductivity grounds due to the high frequency. To operate a single-wire power transmission system, it is nece...
