A magnetic field analysis is developed for three cylindrical conductor bundles in triangular and flat configurations. These configurations are compared from the point of view of per unit length series-impedance, conductor surface magnetic induction field, and conductor current distributions. Results, taking proximity and skin effects into account, are obtained from the magnetic vector potential considering on the one hand, the multi-pole method for the dielectric medium and on the other hand, Fourier series and Bessel functions developments inside the conductors. It is shown that the flat configuration is less affected by magnetic field proximity effects.
