Question:
A single-phase, \(50-\mathrm{kVA}, 2400 / 240-\mathrm{V}, 60-\mathrm{Hz}\) distribution transformer has the following parameters:
Resistance of the \(2400-\mathrm{V}\) winding: \(\mathrm{R}_{1}=0.75 \Omega\)
Resistance of the \(240-\mathrm{V}\) winding: \(\mathrm{R}_{2}=0.0075 \Omega\)
Leakage reactance of the \(2400-\mathrm{V}\) winding: \(\mathrm{X}_{1}=1.0 \Omega\)
Leakage reactance of the \(240-\mathrm{V}\) winding: \(\mathrm{X}_{2}=0.01 \Omega\)
Exciting admittance on the \(240-\mathrm{V}\) side \(=0.003-j 0.02 \mathrm{~S}\)
(a) Draw the equivalent circuit referred to the high-voltage side of the transformer.
(b) Draw the equivalent circuit referred to the low-voltage side of the transformer. Show the numerical values of impedances on the equivalent circuits.
