1. POWER Transformers ARE "RATED" IN MEGAVOLT-AMPERES" NOT "CALLED" 2. SMALL TRAFO ARE RATED IN VOLT-AMPERE (VA) --- 0 TO 999 VA 3. DISTRIBUTION TRAFO ARE RATED KILOVOLT-AMPERE (KVA) --- 1000 TO 999,999 VA 4. POWER TRAFO ARE RATED MEGAVOLT-AMPERE (MVA) --- 1,000,000 VA UP POWER = VOLTAGE X AMPERES = VA POWER = VOLTAGE X AMPERES X P.F.(1) = VA IT IS NOT RATED IN WATTS/KILOWATTS/MEGAWATTS FOR THE LOAD IS NOT DEFINED FOR THE END USERS OR DESIGNERS AND THE POWER FACTOR IS ALSO UNKNOWN. TO BE SAFE, THEY USE 100% P.F. (UNITY) OR 1 FOR RESISTIVE LOAD THATS WHY THE RESULT IS ONLY VOLT-AMPERE. MOTOR OR INDUCTION LOAD ARE USUALLY LESS THAN 1.

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.

What does mva stand for in the turbo generator field?

There are two concerns here regarding loading on transformers of this size. First is the difference between MVA and MW. MW is just real power -- watts. MVA is total power which includes real power (MW) and reactive power (MVAR).--- http://en.allexperts.com/q/Electric-Power-Utilities-2405/operation-limit-oof-power.htm
