VR 1.173% = VR V nl V fl - V fl = Now we can solve for the voltage regulation: V nl 345kV = 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 341kV = V fl V o = The full load voltage is the output voltage, so V i 138 kV = V o 341 kV = We are given the output and the input voltage at full load:
