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

Unformatted text preview: V i 2390 V = V o 242 V = We are given the output and the input voltage at full load: a 10 = a V prated V srated = First find the turns ratio Solution V srated 240 V = V prated 2400 V = S rated 500 MVA = Problem 5-18: MVA 1000 kW kVAR kW kVA kW...
