Answer / praveen

in delta we dont ve neutral, but in star we ve neutral.
in delta initial current is high.
but in star it is only 1/3rd of current in delta

Answer / sn

we dont have neutral in delta connection. In delta line n phase voltage are same but in star phase n line current are same.

Answer / vineet kumar

In star connection insulation of winding is less because phase voltage is 1/root3 of line voltage..
