Why generator is not connecting in delta ..why connecting in star ?..

Answer / guest

In star connection voltage/phase=line voltage/1.73 and emf induced in generator is directly proportional to number of turns. So in star connection we have to use less number of turns & insulation.star connection is most economical than delta

Why generator is not connecting in delta ..why connecting in star ?..

Answer / ajay

Delta have 3rd harmonics which maintain circulating current in closed delta which cause heating effect. 
Y connection provide neutral for installing relays and circuit breakers which are connected in per phase manner.

Why generator is not connecting in delta ..why connecting in star ?..

Answer / narahari

in delta line voltage=phase voltage,but in star connection line voltage=root3*phase voltage then it gives more voltage than in star

Why generator is not connecting in delta ..why connecting in star ?..

Answer / nitin khatana

generator are always connected in star to prevent 3rd harmonics circulating current.another reason is in star connection (v line/root 3 =vph) so insulation thickness requirement is less in star in the given space and slot.
