Compute the efficiency of the transformer, Electrical Engineering

Assignment Help:

Q. These data were obtained from tests carried out on a 10-kVA, 2300:230-V, 60-Hz distribution transformer:

• Open-circuit test, with low-voltage winding excited: applied voltage 230 V, current 0.45 A, input power 70 W

• Short-circuit test, with high-voltage winding excited: applied voltage 120 V, current 4.35 A, input power 224 W

(a) Compute the efficiency of the transformer when it is delivering full load at 230 V and 0.85 power factor lagging.
