heal.abstract	This paper undertakes an analysis of the causes of core vibration in Si-Fe distributed gap wound cores, based on appropriate exploitation of calculated and experimental local flux distributions, intending to propose techniques enabling reduction of the resulting noise. Magnetostriction phenomenon effects, playing an important role in the noise level, can be handled by using appropriate lamination geometry optimization and low stress core building. The magnetic forces in the lap-joint regions, constituting another significant source of vibration, can be reduced by conveniently increasing the clamping pressure. However, special attention has to be paid in optimizing clamping pressure increase, as it accentuates magnetostriction. Finally, it was assessed that the in-plane lamination magnetic forces do not significantly affect core vibrations, at least in the considered core case, corresponding to a typical wound core type distribution transformer. © 2006 IEEE.	en
