Find the tote currents Ia Ib and Ic In a Yconnected load giv

Find the tote currents: I_a, I-b, and I_c In a Y-connected load, given the following; V_an = (150/_0 degree), V_bn = (150/_-90 degree), V_cn (150/_+90 degree), Z_y = 8,

Solution

I an=(150<0)/(8+j2)=18.19<-14 amps

Ibn=(150<-90)/(8+j2)=18.19<-104.03 amps

Icn=(150<+90)/(8+j2)=18.19<75.96 amps
