A balanced star-connected 3-phase load is fed by a balanced 3-phase voltage source through a transmission line, per figure below, calculate: a) Phase voltage of the star-connected load, ZY? b) Active and reactive power drawn by the star-connected load, ZY? c) Power lost in the transmission line, ZL?Vab?=293.94sin(100?t+30?),ZY?=10+j6.28?,ZL?=1.5+j0.15?
Given values for and ,, and so, Now, phase voltage across is given by: put the value of in above equation In star connection per phase voltage is equal to line/(sqrt3).
