A delta connected source delivers power to a delta- connected load shown in Figure (1). The rms line-to-line voltage at the source is 300 V. The load impedance is Z?= (11+j4)?. SHOW ALL FORMULAS used to find your answers.
Find:
a) The current, IaA (Hint: find Wye-Wye equivalent circuit [SEE FIGURE (2)] below and find values VAn and ZY)
b) Find the voltage, VAB
c) Find the current, IAB
d) Find the total power delivered to the loads
e) Find the power lost in the lines
