Abstract
The paper analyzes the magnetic flux density distribution in the vicinity of symmetric three-phase busbars in the presence of a neutral line for four different intermediate positions of „U” busbars and different phase arrangement of currents. The effect of the busbars shielding on the distribution of the magnetic field is also examined. Calculations were performed in the software package “COMSOL Multiphysics” that is based on the finite element method. The obtained results showed that the current phase shift, as well as the position of the busbars change the magnetic field distribution and the enclosure reduces the magnetic field outside the observed system.
