Question

3.
A balanced Y-connected
load having an impedance of 72+j212/q is
connected in parallel with a balanced A-
connected load having impedance of 150 0° /p.
The parallel loads are fed from a line having an
impedance of j122/q. The magnitude of the line-
to-line voltage of the Y-load is 7650V.
a) Calculate the magnitude of the current in the
line feeding the loads.
b) Calculate the magnitude of the phase current
in the Y-connected load.
c) Calculate the magnitude of the phase current
in the A-connected load.
d) Calculate the magnitude of the line voltage
at the sending end of the line.
