Answer / marsad
In a transmission system star connected transformers are preferred than delta connection.. .
Usually the star point is earthed and connected a neutral current transformer in series with the neutral point and ground.. and works as a 3 phase 3 Wire system..
Whenever an internal fault occurs an unbalaced current Flows through the neutral point and then through NCT if the neutral current above a limiting value a relay connected from NCT (called restricted earth fault relay) will actuate.. Which will trip the transformer and protects it.. This can only be done in star connected transformers..

Answer / gravityguru
it provides a point to create potential difference...
between R-N, Y-N. B-N phases....this is in case of 3phase 4
wire system................
hence we can connect balanced or unbalanced load to different
phases
