A 10 KVA single phase transformer, for 2000V/400V at no load, has resistance and leakages reactance as follows: Primary winding: resistance 5.5 ohms, reactance 12Ohms; Secondary winding: resistance 0.2 ohms, reactance 0.45 ohm. Determine the approximate value of the secondary voltage at full load, 0.8 p.f. (Lagging), When the primary supply voltage is 2000V. {Ans: 377.6V] ................
