In the monograph the physical mechanism and the effects of ice forming on the lines of power transmission ? a very dangerous and have enormous economic costs of natural phenomena are examined. Theoretical aspects of a new method of struggle against icing on power lines by connecting to a two- or three-phase power line high-frequency generator are investigated. Propagation of electromagnetic waves along the long line given its dispersion properties and skin-effect are analyzed. By numerical solving of the heat equation are investigated three of process conversion electromagnetic wave into heat: continuous, discrete and continuous pulse-discrete. The device of powerful high-frequency generator is considered and the results of experimental verification of the heating wires by high frequency electromagnetic waves are provided. Level of electromagnetic radiation from a two-wire line is calculated. Advantages of the new method of struggle against icing on power lines with ice melting...
