Purpose of the work - the development of the theoretical foundations of the modeling, measurement, calculation and reduction to a safe level of an external magnetic field of high-voltage AC power lines to solve electromagnetic problems of ecology. Methods - mathematical, computer and physical simulation of an external magnetic field of power lines. The world's known methods of modeling, measurement, calculation and reduction of the external magnetic field of overhead and cable power lines were analyzed. Proposed the mathematical model of high-voltage transmission lines and cable lines as the magnetic field sources with regard to their design features. The experimental field and laboratory studies of the magnetic field of power lines were done. Offered constructive-technological methods of reducing the magnetic field of overhead power lines and cable lines, methods of passive and active shielding magnetic field. The scientific and methodological bases of calculation of the magnetic field of power lines, methodical bases of designing of high voltage overhead transmission lines and cable lines alternating current with a reduced level of the magnetic field, the scientific basis for the creation of effective passive and active electromagnetic screens were elaborated. Developed and implemented in the energy sector of Ukraine recommendations for the calculation of the magnetic field of power lines, teaching the basics of transmission lines with a safe level of the magnetic field.
