The above specifications are for unity power factor loads. Although regulation is not affected by power factor, the nominal
voltage does change. A lagging power factor will cause the nominal voltage to drop while a leading power factor causes the
nominal voltage to rise. The voltage variation with power factor is shown in Figure 3.
