What would be the ratio of a Delta-Wye tranformer having 48000 volts phase to phase on the primary..

Answer / nain

voltage for delta side will b measured line voltage(phase
to phase)
voltage for star side will b measured phase voltage(phase
to neutral)
as u hav given both line voltages so for star side v will
convert that to phase voltge i.e.4160/1.73=2404.62

so ratio=48000/2404.62=19.96
