The following data are obtained when open-circuit and short-circuit tests are performed on a single-phase, \(50-\mathrm{kVA}, 2400 / 240\)-volt, \(60-\mathrm{Hz}\) distribution transformer.

(a) Neglecting the series impedance, determine the exciting admittance referred to the high-voltage side.

(b) Neglecting the exciting admittance, determine the equivalent series impedance referred to the high-voltage side.

(c) Assuming equal series impedances for the primary and referred secondary, obtain an equivalent \(\mathrm{T}\)-circuit referred to the high-voltage side.
