So given is that you have a balanced delta connected voltage source with negative sequence and an unbalanced wye connected load (with neutral line). Al the loads are given , the neutral current is given and the first phase voltage of the soure as Vp=Vm<10°. Asked: Ia,Ib and Ic and the Power measured by both wattmeters.
So I found 2 equations by doing mesh analysis and 1 equation as KCL in the neutral point (for 3 unkowns). But my last equation: 9,02+j4,53= -(Ia+Ib+Ic)= -(Ia-Ic-Ia+Ic)=0 so I wonder what I did wrong ? Thank you
