What is the formula for calculating Transformer Losses &
Efficiency. I want to compare the Transformer efficiency at
different loading condition.

Answer Posted / prof dr lehaz kakakhel

go for two tests
open and short circuits tests
From the open, u compute the core power loss and from the
short, u get copper losses. then the formula is
efficiency = output/ (output + the above two losses)

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?
