Since the voltage regulation is negative, we can conclude that the load has a leading power factor VR 1.24 - % = VR V nl V fl - V fl = Now we can solve for the voltage regulation: V nl 239V = V nl V i a = The no-load voltage will be the input voltage referred to the secondary side, which is done by dividing by the turns ratio: V fl 242V = V fl V o = The full load voltage is the output voltage, so
