why stator winding of synchronous machine are connected in
star connection ?
The stator windings are connected in star because for the
same line voltage generated in an alternator or fed in case
of a motor the per phase voltage induced will only be
v/1.732 , hence the no. of turns required will be less and
hence the copper material required will also be less ,
besides te star connection also enables the provision of a
neutral which can aid in safe passage of fault currents .

Hi, I'm running plastic reprocessing company where all motors are running only in delta. Due to that when I use start my 30 hp motor my transformer gets fuse. Where it happens two times a day. I gt a suggestion from a person about Automatic Power Factor Controller APFC. Is it useful for my problem??? Or is der any other way for solving this problem?? Upgrading the transformer is difficult. Pls give Me ur suggestion. Waiting for ur reply.
