Three identical single phase transformers, each rated at 100KVA, 7KV/3.5KV, 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 200kVA, wye connected load is attached across the secondary winding.
Compute the ratio of the line to line voltages and the line current on both sides of the transformer.
