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.
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.

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.

I have a project now, a 6 MVA 13.8KV/6.6KV transformer costs about $16,000.
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
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.
There is no reason why it shouldn't be. However, the correct symbols are:kV.A not kvaMV.A not mva
A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.
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.
