Determine the required voltage at the high-voltage terminals, Electrical Engineering

Assignment Help:

Q. A 20-kVA, 2200:220-V, 60-Hz, single-phase transformer has these parameters:

Resistance of the 2200-V winding R1 = 2.50 

Resistance of the 220-V winding R2 = 0.03 

Leakage reactance of the 2200-V winding X1 =0.1 

Leakage reactance of the 220-V winding X2 = 0.1 

Magnetizing reactance on the 2200-V sideXm = 25,000 

(a) Draw the equivalent circuits of the transformer referred to the high-voltage and low voltage sides. Label impedances numerically in ohms.

(b) The transformer is supplying 15 kVA at 220 V and a lagging power factor of 0.85. Determine the required voltage at the high-voltage terminals of the transformer.
