A 25-kVA, 2300:230-V, 60-Hz, single-phase transformer has the following parameters: resistance of high-voltage winding 1.5 Ω, resistance of low-voltage winding 0.015 Ω, leakage reactance of high-voltage winding 2.4 Ω, and leakage reactance of low-voltage winding 0.024 Ω. Compute the following:
(a) Equivalent series impedance referred to the high-voltage side.
(b) Equivalent series impedance referred to the low-voltage side.
(c) Terminal voltage on the high-voltage side when the transformer is delivering full load at 230 V and 0.866 power factor lagging.
