Question 1
A Y-connected source supplies power to two combinations of Y-connected and Y-connected
loads in a three-phase balanced system in negative sequence. Given that the line impedance
is (1+j2)  per phase while the load impedances are (5+j3)  per phase and (7–j4)  per
phase for both Y-connected load. Given the line current flow through (7–j4)  is 𝐼𝑐 = 4∠ −
20°𝐴. Evaluate :
i. the total of impedance
ii. both line and phase voltage and current for each loads
iii. both line and phase voltage drop at lines
iv. line voltage supply
