Transformer is breathing like human. When air is going
inside it contain moisture. To avoid short circuit due to
moisture, breather is used. When air passes through breather
it became dry. Result long life of transformer

Dear Sir/Madam, I have one questions we have three steam turbines and one Gas turbine and our industry linked with the public network, we have protection system one of the protection is reverse power we can export just four MW only i would like to ask about how to calculate the reverse power. Thank you in advance best regards
