The influence of changing the distance between the conductors and screen on the total magnetic field of shielded three phase flat high current busduct

Kusiak D., Piątek Z., Szczegielniak T.

No. 65

25--32

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.
