Question:

A bank of three single-phase transformers, each rated 30 MVA, \(38.1 / 3.81 \mathrm{kV}\), are connected in \(\mathrm{Y}-\Delta\) with a balanced load of three \(1 \Omega\), Y-connected resistors. Choosing a base of 90 MVA, \(66 \mathrm{kV}\) for the high-voltage side of the three-phase transformer, specify the base for the low-voltage side. Compute the per-unit resistance of the load on the base for the low-voltage side. Also, determine the load resistance in ohms referred to the high-voltage side and the per-unit value on the chosen base.
