METHOD OF DETERMINING OPTIMUM THICKNESS OF SHEETS OF MAGNETIC CONDUCTOR OF TRANSFORMER Russian patent published in 2025 - IPC H01F3/04 H01F27/25 G01B7/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to electrical machines, and can be used to reduce their idling losses. Method of determining the optimum thickness of the magnetic conductor of a transformer consists in measurement of losses in the magnetic conductor by an open-circuit test for two values of the thickness of the sheets at one frequency at nominal and reduced voltages for two values of the thickness of the sheets. Optimum thickness of sheets during operation of transformer with nominal voltage is determined by formula

where P_n1 is loss in magnetic core with thickness of sheets δ₁ at nominal voltage U_n; P_r1 is loss in magnetic core with thickness of sheets δ₁ at reduced voltage U_r; P_n2 is loss in magnetic core with sheet thickness δ₂ at nominal voltage U_n; P_r2 is loss in magnetic core with sheet thickness δ₂ at reduced voltage U_r; m=U_r/U_n.

EFFECT: possibility of reducing magnetic losses in the transformer due to optimization of the thickness of the magnetic conductor sheets.
