Wireless selection of energy from highvoltage overhead electrical power transmission lines for power autonomous devices

In the work has investigated the possibility of wirelessenergy selection from highvoltage overhead electrical power transmission line with help of aTesla flat coil, to be placingneartheelectricalline wire at a distance of tens of centimeters to two meters. For magnification the efficiency of energy selection using a Tesla coil, have proposed to be placing in the interval between the turns a ferromaterial with alargemagnetic permeability.The theoretically justified possibility of magnification the voltage on such a coil by many oftimes to voltages and powers, sufficientfor power supply of various lowpower devices isshown.
