Answer Posted / dolphinopera
in transformers the
starting and finishing
end of the phase
windings are brought
out. hence you can
connect the windings
either in star or in
delta. another
important thing, if the
star winding is used
without neutral there
is a possiblity of
damage of winding.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
