Influence of Eddy Currents on the Magnetic Field of the Flat Three Phase High Current Busduct

For two parallel conductors the magnetic field in their external areas with taking into account the reverse reaction magnetic field generated by eddy currents induced on conductors was calculated. It let determinate of the total magnetic field outside of tubular conductors of the flat three phase high current busduct. Into account was taken the external proximity effect. Influence of eddy currents on the total magnetic field was appraised through relation of the total magnetic field on the external surface of conductor to the modulus of the field determinate without taking into account the reverse reaction magnetic field, thus without taking into account eddy currents induced on conductors. Relation this was shown by charts for every of phases, in function of parameter, considering of current frequency, electrical conductivity and transverse dimensions of tubular conductor. Into account was taken, that magnetic field is a rotating elliptical field and his modulus is equal value of semi-axis of ellipse.
