There is one 40MVA oil cooled transformer (yet to
commission), filled with 95% oil and we are trying to fill
5% Nytrogen in that transformer so that there should not be
any foreign component inside. But even though there is no
leakage, nytrogen is not withstanding inside transformer,
within a day or two pressure guage is showing 0. Why is it
soooo? Pls reply.
