This paper presents an alternative to characterize the material of magnetic circuit of an existing transformer. The proposal aims to generate an alternative to standardized methods (IEC 60404-2: 2008 and IEC 60404-3: 2009) in those cases in which a sample of material is not available. The magnetic flux density (B) and the magnetic field (H) are mathematical modeled from electrical variables. Experimental results show that the presented technique is adequate to characterize magnetic materials.
