Transformer are always rated in Kva because there are 2
losses in transformer.
one is copper loss which depends on current & the other is
iron loss which depends on voltage & not affected bypower
factor.
Thus transformer rating in kva & not in kw.

if the motor rated speed is 950rpm. how to change the above rated speed? is it possible?

Dear sir, In our plant have Station Transformer having capacity,i want to know, why LV side 40 - 40MVA is given? & how we can get 6.3 KV supply from tertiary(i.e. Open delta connection), Vector Group YNyn0 - yn0 +d MVA Rating 80MVA / 40 - 40MVA + 26.7MVA Voltage rating 420 (Tap range +6,to -10)81.25% /11.5KV - 11.5KV +6.3KV
