Question:

The reactance of a generator, with the nominal specifications of \(14 \mathrm{kV}\) and \(500 \mathrm{MVA}\), is \(1.1 p . u\). Determine its impedance in percent if \(20 \mathrm{kV}\) and \(100 \mathrm{MVA}\) are chosen as the base voltage and power.

1) \(30.8 \%\)

2) \(10.78 \%\)

3) \(60.8 \%\)

4) \(57.8 \%\)
