eng Rotational magnetisation
Zurek, Stan
Transformers Magazine Vol. 2, No. 2, 2015
Rotational magnetisation is a phenomenon that occurs locally in the magnetic cores of three-limb transformers. The power loss dissipated under rotational magnetisation can be several times higher than under usual magnetisation conditions as defined by manufacturers of the electrical steels. The phenomena were discovered over 100 years ago and have been studied since, but it is difficult to model it theoretically and apply the knowledge practically in transformer design. This article focuses on the definition and discussion of the phenomenon in...
