thumb_up100%
A balanced, 3-phase, 346.41 Vrms line voltage source feeds two loads connected in parallel with a 3-phase line with j3ohm/phase impedance.
The first load is Y (star) connected and has an impedance of 12ohm/phase.
The second load is D (delta) connected and has an impedance of 12ohm/phase.
Taking the Van phase voltage as reference:
a)Find the current, active power and reactive power provided by the source.
b)Find the phase and line voltages on the loads
c)Find the phase currents for each load
d)Find the active and reactive power in each load.
e)Find the active and reactive power loss in the line
f)Show whether the total active and reactive power provided by the source is equal to the total active and reactive power in each load and line.
