Will The Rated Capacity of 20 MVA ,220/6.6 KV, ONAN
cooling Power Tranformer be increased up to 25 MVA with
respect to its %Impedence by ONAF cooling with same
rating..?
Answer Posted / appana ravi kumar
if we are using ONAF transformer , the winding temperature
of the transformer can be controlled , so the transformer
impedence also increase . transformer can be run above the
full load.
