1. The problem statement, all variables and given/known data An Unbalanced 3-phase star connected load has the details as below. Line Voltage=400V Voltage R-N = 230V 0° Voltage B-N = 230V +120° Voltage W-N= 230V -120° Impedance R-N = 100+J36 Impedance B-N = 102+J0 Impedance W-N = 50+J0 A.) Determine the neutral current(im confident in this) B.) Determine the voltage between the star point and neutral wire if the neutral wire(Vn-o) becomes disconnected. (Im not sure how to do this) 2. Relevant equations 3. The attempt at a solution I calculated neutral current. converted all impedances to polar to calculate current Ir=Vph/Zr=230V 0° / 106.28ohm 19.8° = 2.1641A -19.8° Ib=230V 120° / 102ohm 0° = 2.25A 120° Ic=230V 240° / 50ohm 240° = 4.6A 240° Converted these to Rectangular hen Added them together to determine neutral current Ir=2.16A -19.8°=2.0361-J0.733 Ib=2.25A 120° =-1.125+J1.95 Iy=4.60A 240° =-2.3-J3.98 (2.0361-J0.733)+(-1.125+J1.95)+(-2.3-J3.98) = -1.3889-J2.7631 = 3.09A -116.69° Now i do not know how to approach question b.) Determine the voltage between the star point and neutral wire if the neutral wire(Vn-o) becomes disconnected.
