Compute the effective armature, Electrical Engineering

Assignment Help:

For a 45-kVA, three-phase, wye-connected, 220- V synchronous machine at rated armature current, the short-circuit load loss (total for three phases) is 1.80 kWat a temperature of 25°C. The dc resistance of the armature at this temperature is 0.0335  per phase. Compute the effective armature ac resistance in per unit and in ohms per phase at 25°C.
