Frequency Spectrum Analysis of Magnetic Field Strength for Effective Condition Monitoring of Magnetic Cores

Bahmani, Hamed

Abstract

This paper presents a new approach for Inter-laminar Fault (ILF) analysis and condition monitoring of magnetic cores with Grain-Oriented Electrical Steels (GOES). The proposed technique relies on interpreting frequency spectrum of the magnetic field strength over one cycle of magnetisation. Experimental work was undertaken on stacks of four standard Epstein size laminations subjected to artificial ILFs of different severity. Impacts of each fault scenario on the magnetic field strength in time and frequency domains were studied. This approach can effectively increase accuracy of fault diagnosis, and improve detectability of weak fault signatures in magnetic cores.
