A transformer this size will usually come with a test report which will give this information. Depending on the configuration, it may give zero seqence and positive sequence impedances.
mw/mva=power factor reactive power(Q)=I2XL or E2/XL where XL= REACTANCE apparent power = square root of (MW2 + MVAR2 )
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
Large transformers are filled with oil which circulates to a radiator to get rid of excess heat. A 100 MVA transformer should waste about 1 MW of power on full load, 0.5 MW on no load.
VA or KVA or MVA
Ece 63 mva.
Transformer does not convert MVA to KV. MVA is unit of power, where as KV is unit of Voltage. Transformer converts voltgae. Step up or Step down.
800 MVA
The power in a 15 MVA (15000 KVA) transformer depends on the power factor. You did not specify the power factor, so I will assume a power factor of 0.92. Simply multiply MVA by PF and you get 13.8 MW.
I have a project now, a 6 MVA 13.8KV/6.6KV transformer costs about $16,000.

MVA is the aparant power.
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
MVA is the apparent power. MVA=( MW+ MVAr)1/2
