2 6515some ac motor's direction get change dueto ghanging input to the ac drives.(say ryb to rby). but some motor direction remains the same when phase sequence is changed fromdive side. can anybody guide me?
1 5002There 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.
