Abstract

This paper proposes a new approach to an old challenge in the magnetic cores of power transformers and other magnetic devices with grain oriented electrical steels. The main aim of this paper is to evaluate effects of inter-laminar faults of different configurations on dynamic performance and dynamic energy losses of the magnetic cores with grain oriented silicon steels. In the relevant studies, artificial short circuits of different configurations were applied between the laminations of stacks of four Epstein size laminations of 3 % grain oriented silicon steel. The results showed that, inter-laminar fault evaluation and core quality assessment can be effectively done by interpreting the dynamic hysteresis loops of the cores.
