Three single-phase transformers are connected to form a delta-star three-phase transformer of \(110\;kV/\;11\;kV\). The transformer supplies at \(11\;kV\) a load of \(8\;MW\) at \(0.8\;p.f.\) lagging to a nearby plant. Neglect the transformer losses. The ratio of phase currents in delta side to star side is |
