This paper shows how the shift of the axes of both conductors and screen influences the total magnetic field of the three-phase fiat shielded high-current busduct in the screen and its surroundings. Components of this field were expressed through modified Bessel's functions as a function r and Θ of cylindrical coordinates. This phenomenon has been described with the formulas relevant to the relative values of the field and the parameters allowing the frequency,conductivity, and the cross-section dimensions of conductors. Into account was taken skin and proximity effects, and that the magnetic field is a rotating elliptical field.
