Answer Posted / karthikeyan
ACB there is a limit of current may pass through the contact machanism.High voltage side not possible to connect the ACB.
ACB max voltage can be maintained up to 415 volts that means it is purely applicable in LT side.
OLTC not possible to connect in secondary side because secondary side there is a continious load connecting that cause a huge problem may occur in sec side.

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?
