LV Losses - Summary

Very high load losses in the LV winding have been observed. The LV winding was built following the “classical” design rules for the transposition of conductors in parallel. However, only simulations can verify the validity of the “classical solution” for each specific design.
Simulations show that the flux leakage pattern is not symmetrical and with significant radial components.
The radial transpositions in the LV winding, determined by means of classical rules are not sufficient to keep circulating currents under control. The axial positioning of transpositions minimizing the losses without additional costs for the winding is determined.
