The Y-Y system of Fig below has a balanced load and a +j 20. If the line voltage at the generator is 16,000 V and the total power delivered to the load is 1200 kW at 80 A, determine each of the following: 

a. The magnitude of each phase voltage of the generator. 

b. The magnitude of the line currents. 

c. The total power delivered by the source. 

d. The power factor angle of the entire load "seen" by the source. = 

e. The magnitude and angle of the current La if EAN EAN 40°. 

f. The magnitude and angle of the phase voltage Van

g. The impedance of the load of each phase in rectangular coordinates. 

h. The difference between the power factor of the load and the power factor of the entire system (including Zline). 

i. The efficiency of the system.
