Wireless Technology of Electric Power Transmission Using Non-Metal Conductive Media

Over two million kilometers of power grids in Russia exist. They have to be replaced in the coming 15 years. However, nowadays we witness and participate in the development of advanced technologies. New wireless resonant electric-power systems for different power consumers are considered including stationary single-conductor transmission lines and single-trolley and noncontact high-frequency electric transport, using non-metal conductive media. The trends of the future development and application of wireless resonant systems for electric power transmission are described. In the future, electrified mobile robots with external wireless electric power supplies will allow the organization of agricultural production with full automation of technological processes. The chapter describes the method and means for electric power transmission without metal wires. In this case, several components of conventional transmission lines, such as metal wires, insulators, and cables, are excluded, which results in considerable reduction in the equipment cost.
