Answer / ittu

In delta their is no neutral point.
In star v can find it.

Answer / alen

Delta is when we need much power from motor but in star we
need only the speed.

Answer / sameer

In delta connection line voltage= phase voltage,VL=Vph and
line current=√3phase current, IL=√3Iph.


In start connection Line voltage=√3 Phase voltage ,
VL=√3Vph and line current=Phase current,IL=Iph and in
this connection we got star or neutral point.

Answer / yash sharma

star connection - phase voltage is 1/1.73 times line voltage so speed will be less and required insulation will be low , hence saving of copper achieved. now for delta start you motor which is in your mind!!!!

ster speed slow
