Three balanced three-phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 400 + j300 N/; load 2 is A-connected with an impedance of 2400 + j1800 N/þ; and load 3 is 172.8 + j2203.2 kVA. The loads are fed from a distribution line with an impedance of 2 + j16 N/p. The magnitude of the line-to-neutral voltage at the load end of the line is 18√3 kV.

Question
Three balanced three-phase loads are connected in
parallel. Load 1 is Y-connected with an impedance of
400+ j300 /; load 2 is A-connected with an
impedance of 2400 + j1800 N/þ; and load 3 is
172.8+ j2203.2 kVA. The loads are fed from a
distribution line with an impedance of 2 + j16 N/þ.
The magnitude of the line-to-neutral voltage at the
load end of the line is 18√3 kV.
