Consider the transformer connections in a part of a power system shown in figure. The nature of transformer connections and phase shifts are indicated for all but one transformer. Which of the following connections, And the corresponding phase shift θ, should be used for the transformer between A and B?
1
star – star (θ = 0°)
2
star – delta (θ = -30°)
3
Delta – star (θ = 30°)
4
Star – Zigzag (θ = 30°)
