Three identical single-phase transformers each rated at 100 kVA, 7 kV/3.5 kV are connected as a three-phase transformer bank. The high-voltage side of the transformer is connected in delta and the low-voltage side is connected in wye. A 200 kVA, wye-connected load is attached across the secondary winding. Compute the followingA) Ratio of the line-to-line voltagesB) Line current on both sides of the transformer.
