mega volt amperes
1 MVA = 1000KVA, 1KVA = 1000VA
VA is equivalent to Voltage times current; it includes both real (watts) and reactive (vars) power; In techno speak it is the vector sum of real and reactive power. Thus it is a useful term for calculating the size of equipment necessary, since equipment must be sized for total current flow (both real and reactive contribution).
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.
You would have to know the Power Factor, normally designated PF. MVA x PF = MW. If the PF is unity then MVA = MW. A PF of UNITY suggest the load is purely resistive with neither capacitive nor inductive components in the load or source. Of course this can mean such components have been balanced artificially.
By definition, MVA is equivalent to the vector sum of MW and MVAR: MVA^2 = MW^2 + MVAR^2 = 2500 MVA = 50
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.
You cannot. An ampere (A) is used to measure current. A millivolt ampere (mV.A) is used to measure apparent power. These are two different quantities, so you cannot convert one unit into the other!
MVA is the aparant power.
MVA is the apparent power. MVA=( MW+ MVAr)1/2
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.

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
mw/mva=power factor reactive power(Q)=I2XL or E2/XL where XL= REACTANCE apparent power = square root of (MW2 + MVAR2 )
800 MVA
MVA we are so tight MVA not supposed to fight MVA we are so cool MVA we act like fools. MVA stands for Martina Victoria and Anaya. Bianca not included

Do you mean 'megavolt ampere' (MV.A) or 'millivolt ampere' (mV.A)? By using the incorrect symbol ('mva'), this is not clear.To determine the apparent power, in volt amperes, you divide the true power, in watts, by the power factor of the load. One volt ampere is one-millionth of a megavolt ampere ('MV.A' -not 'mva') -assuming you don't mean 'millivolt ampere' ('mV.A')!
MVA in Asia was created in 1968.
MVA in Asia's population is 500.
