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.
