The secondary side is rating of 200v,if you considering
loop the net current flowing throw winding increases hence
losses also increases and winding over heated,if it so on
for hours winding insulation may failed.And another one is
core is nearer to low winding,due to high voltage core
losses and core insulation between laminations also failed.

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?
