Abstract

In this paper, general mathematical model with relevant factors to investigate the magneto mechanical coupling in magnetic core are considered. Experimental measurements of vibration and audible noise in amorphous steel cores of the transformer have been carried out. The results of the mathematical model were compared to the results of simulation by finite element method (FEM) of the previous research and experimental measurements. Magnetostrictive noise and vibration levels in the amorphous steel core have been identified higher than silicon steel core. Experimental results have shown the use of iron clamps on the leg and yoke with a reasonable clamping force permits a reduction in vibration amplitude and noise.
