A 3-phase 25 kVA, 208 V, 60 Hz, alternator (generator) is operating under balanced conditions and supplies a current of 20 A per phase at 0.8 lagging power factor to a load at rated voltage. Remember the convention for 3-phase voltages and currents.
a) Draw the 3-phase circuit when the load is connected in Y and when it is connected in delta. (You don't need to calculate Z_p here.)
b) Draw the single-phase equivalent circuit, label the voltages and currents, and give their values.
c) Draw the power triangles (total 3-phase power and per phase power) for the system as described.
d) Calculate Z_p for the single phase equivalent circuit.
