how much loading in terms of ampere can put on 5 MVA,33/11
KV TRANSFORMER having rated current 263 Amp ?????????

Answer Posted / jayant subhash golait

If the word rated current comes,then it is actually safe n maximum permissible limit....Obviously,the machine will misbehave when crossed this limit...to save the machine or to avoid failures,extra cooling may be required that is also within tolerable range...again the manufacturer may declare that value as a rated current which is itself little bit away from tripping or breakdown or danger zone of tolerance....finally ,it is solely depend upon manufacturer n in turn the quality of raw material used to design the machine....
