Question: A balanced Y-Y four-wire system has phase voltages Van = 120 0 Vbn = 120 - 120 Vcn = 120 120 V The load

A balanced Y-Y four-wire system has phase voltages
Van = 120 ∠0°
Vbn = 120 ∠ - 120°
Vcn = 120 ∠120° V
The load impedance per phase is 19 + j13 Ω, and the line impedance per phase is 1 + j2 Ω . Solve for the line currents and neutral current.
