Influence of transformer lamination from amorphous steel on permeability disturbance by transformers
Konečný, Pavel ; Ertl, Jakub (referee) ; Pavlík, Josef (advisor)
Influence of transformer lamination from amorphous steel on permeability disturbance by transformer This diploma work is about difference between current materials and amorphous plates which are used as pivots of transformers. Samples are tested by frequence 50-2500 Hz. By using more suitable materials we avoid the unallowable electromagnetic interruption better and we get more positive continuance of the retroactivity on the net.

In this paper, a new modification of a commercial apparatus Edwards Coating system E306A is described that enables to perform diffusion measurements with radioactive tracers. The plan-parallel thin layers are removed by sputtering with Ar+ ions and the well defined fraction of the sputtered-off material is sequentially collected. The function of the apparatus is exemplified by the measurement of bulk diffusion coefficient of 65Zn in Fe40Ni40B20 alloy at T = 684 K.
