Three phase alternator having three coil(three Pole or multiple of 3 pole) placed in a circular armature Angle = 360/3= 120
. Each coil act as a single phase alternator
In Scott connected transformer having two identical transformer, teaser transformer having 86.6% (0.5√3) of primary turns than main transformer
Expression for primary voltage
V1 = Vp Sin(ɸ +0)
V2 = Vp Sin(ɸ +120)
V3 = Vp Sin(ɸ +240)
Expression for secondary voltage
