importance of air gap in transformer

Answer Posted / arockia doss.a

Actually the airgap in transformer is for transfer the
primary power to the secondary. Means the primary winding
input voltage level will be step up/down(Depends on type of
trf.) to the secondary winding.

This is exactly same with wats happening in a 3 phase ind.
motor between stator & Rotor.

Thats why we are calling ind. motor as "Rotating Trf".

Thanks ....

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?
