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).

How much power in a 15000 kva 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.
How do you convert MVA into 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.
A transmission line has 30 megawatts and 40 megavars what is the megavolt amps load on the line?
By definition, MVA is equivalent to the vector sum of MW and MVAR: MVA^2 = MW^2 + MVAR^2 = 2500 MVA = 50
What is the capacity of power transformer for 132kva substation?
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.
How do you convert amps to 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!
What kind of power is MVA?
MVA is the aparant power.
What does mva mean in electrical terms?
MVA is the apparent power. MVA=( MW+ MVAr)1/2
Is mvar can used to measure mva?
No, mvar (megavolt-ampere reactive) is a unit of apparent power while MVA (megavolt-ampere) is a unit of real power. Mvar is used to measure reactive power, while MVA is used to measure total power (both real and reactive).
How transformer converts mva to kv?
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.
How much power in a 15000 kva 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.
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
What is the maximum capacity of power transformer at 220kV voltage?
800 MVA
How do you calculate MVAR with mw and mva?
mw/mva=power factor reactive power(Q)=I2XL or E2/XL where XL= REACTANCE apparent power = square root of (MW2 + MVAR2 )
What is MVA at Plaza?
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
How do you convert MVA into 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.
How do you convert volts to mva?
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')!
How many mega volt ampere are there in a 1 mega watt generator?
In a 1 megawatt (MW) generator, the unit of power is given in terms of megawatts, which represents one million watts. A megavolt-ampere (MVA) is a unit of apparent power equal to one million volt-amperes. Therefore, in a 1 MW generator, the apparent power rating would also be 1 MVA, as the apparent power rating is typically equal to the real power rating in a generator with a power factor of 1.
