Problem P15.75

A 60-Hz 20-kVA 8000/240-V-rms transformer has the following equivalent-circuit parameters: Primary resistance R1 15 Secondary resistance R2 0.02 Primary leakage reactance X1 = L1 120 Secondary leakage reactance X2 = L2 0.15 Magnetizing reactance Xm = Lm 30 k Core-loss resistance Rc 200 k Find the percentage regulation and power efficiency for the transformer for a rated load having a lagging power factor of 0.8.
