GATE Electrical Engineering (EE) 2016 Shift 2 Solved Paper

Three single-phase transformers are connected to form a delta-star three-phase transformer of $110\mathit{k}\mathit{V}∕11\mathit{k}\mathit{V}$. The transformer supplies at $11\mathit{k}\mathit{V}$ a load of $8\mathit{M}\mathit{W}$ at $0.8\mathit{p}.\mathit{f}.$ lagging to a nearby plant. Neglect the transformer losses. The ratio of phase currents in delta side to star side is
