Question
Determine the main dimensions of the core, the number of turn and cross-section of conductors for a 5 kVA, 11000/400 V, 50 Hz, single phase core type distribution transformer. The net conductor area in the window is 0.6 times, the net cross-section iron in the core. Assume a square cross section for the core, flux density $1 \text{ Wb/m}^2$, a current density $1.4 \text{ A/mm}^2$, and a window space factor 0.2. The height of window is 3 times its width.
