open delta question

[JRedekopp]

In an open delta with a center-tapped transformer, label the two ends of the center-tapped transformer as L2 and L3 and label the high leg as L1. The current flow in the neutral (center tap) is


AN = A1 – (A2 + A3)

AN = A1 + (A2 – A3)

AN = A1 – (A2 – A3)

AN = A1 + (A2 + A3)
