Assignment Help:

What are eddy currents? State how their effect is decreased in transformers.

(b) Verify the ef?ciency of a 15 kVA transformer for the following conditions:

(i) full load, unity power factor

(ii) 0.8 full load, unity power factor

(iii) half full load, 0.8 power factor.

Suppose that iron losses are 200Wand the full load copper loss is 300W.
