The characteristic properties of magnetization processes of 3% SiFe sheets in transformer cores

Multiscale modeling of the magneto-mechanical behavior of grain-oriented silicon steels

“…Few results are available in the literature concerning the magnetostrictive behavior when the magnetization is applied along TD. We can only report the observations of Sheiko et al [27] whose results are in good accordance with ours.…”

Estimation of the Clamping Pressures of Transformer Windings from Vibration Measurements

“…These forces, deriving from the ac excitation, result in vibrations whose magnitude is affected by the clamping pressure (Antipov et al, 1996;Berler et al, 2000). However most studies of the vibrations generated in transformer cores have been aimed at designing transformers which would generate less audible noise (Schuller, 1982;Reiplinger, 1980;Eingorn, 1989;Sheiko et al, 1996) and much of this work was of a theoretical nature with relatively little actual measurement of vibration levels.…”
