we use Dyn11 trafo for distribution purpose, if it`s possible
for replacing Dyn1. if it`s change means what will happen?
If this transformer works in parallel with other
transformer of the same connection type it is not possible
–the angle between supplied voltage will be 300 degrees [or
60 degrees] and will provoke a short-circuit equal to
Vstator/2/Ztrf .
If the transformer works alone it will be ok [no any
difference]

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?
