Question

Determine the main dimensions of the core, the number of turns and the cross section of conductors for a 5 KVA, 11000/400V, 50 HZ, single phase core type distribution transformer. The net conductor area in the window is 0.6 times the net cross section of 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.
