A 9375-kVA, 13.8-kV, 60-Hz, two-pole, Y-connected synchronous generator is delivering rated current at rated voltage and unity PF. Find the armature resistance and synchronous reactance given that the field excitation voltage is 11935.44 V and leads the terminal voltage by an angle of 47.96°.

Step 1
The apparent power S is given by the formula S = V * I, where V is the voltage and I is the current. We can rearrange this to find I = S / V. S = 9375 kVA = 9375000 VA V = 13.8 kV = 13800 V So, I = 9375000 / 13800 = 679.71 A Show more…
