What would be the ratio of a Delta-Wye tranformer having
48000 volts phase to phase on the primary and 4160 volts
phase to phase on the secondary?
Answers were Sorted based on User's Feedback
48000/(4160/1.732)=19.99
Ratio may be taken as 20.

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
