7. A transformer core is shown in cartoon form in Figure 8.26. This is made up of, perhaps implausibly, 29 gage M-36 laminations: the same sort of material described by Figures 8.19 and 8.20. Assume a density of 7,700 kg/m. Dimensions as called out in the figure are: Core central column width Wc 250 mm Window width W 250 mm Window height h 500 mm Depth D 250 mm The primary winding of this core is wound with 96 turns. It is connected to a 60 Hz voltage source of 2,400 V, RMS. (a) How much current does the winding draw? (b) How much power is dissipated in the core? h W WC Figure 8.26 Transformer core D 7.
