Answer / sharib hussain
For making a scott connection as a four wire (having
neutral point), the teasor transformer is tapped for
neutral in such a way that the line voltage = 1.732 times
phase voltage.
By looking into phasor diagram u will come to know that the
neutral must be present at the position it divides the
primary of teasor transformer in the ratio of 2:1
and hence it is tapped at 86.6%

Answer / rahul ruhela
Scott connection changes three phase to two phase supply.by
taping 87% and 50% tapping its provides 90 degree phase
difference in output two phase supply which is essential to
two phase system

Answer / murali
The cause for that is to produce 100℅ of o/p voltage ...I mean √(0.866sqr)+(√0.5sqr) ...

Answer / shahid
now a days three phase supply are available, but For the
two phase load, we are using scott connection of
transformer.
