A 500-KVA, 11000/400-V, Three-phase, Yd-connected transformer has the following parameters per phase: R1 = 1.579 2, R2 = 0.0022, RC2 = 342.759 , X1 = 6. 316 02, X2 = 0.02 02, XM2 = 34.819 , What would be the readings of the instruments if no-load and full-load tests were to be carried out on the appropriate sides of the transformer in order to determine the full-load efficiency (Note! It is desired that the full-load test would be done at 80% of full-load)?

Answer rating: 100% (QA)

So to determine the fullload efficiency of the transformer youll first need to conduct noload and fullload tests on the appropriate sides Now that the ... View the full answer
