Consider a balanced three-phase system where the sources areconnected in a wye formation and the load is connected in a wyeformation with impedance ZPY for each phase. The"a" phase source voltage isVan=220<0oVrmswith a source impedance of 0Ω. The line impedance foreach phase is 1-j1Ω. If the total complexpower(S3φ) supplied by the sourceis 7260VA at a power factor of 0.6 lagging, answer the followingquestions:
A)Draw the single phase equivalent circuit.
B)What is the combined realpower(P3φ) absorbed by the three-phase load and the power lines?
C)What is the line current,IaA?
D)What is the impedance of one phase of the load,ZPY?
