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.

â 11y agoThe symbol, MV.A (not 'MVA') represents megavolt amperes, and is a multiple of the volt ampere, used to measure the apparent power of a load.
The symbol, MW, represents megawatts, and is the multiple of the watt, used to measure the true power of a load.
These are two different quantities, so you cannot simply 'convert' one to the other. However, the relationship between the two is expressed by the equation:
True Power = Apparent Power x Power Factor
...where power factor is the cosine of the phase angle, that is the angle by which the load current either lags or leads the supply voltage.

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
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.
Convert mw to kwh?
mw (mega watt) is one million watt and that is a unit of electricity, whereaskwh(kilowatt hour) is rate of consumption of one thousand watt of electricity for one hour.AnswerFirst of all, let's get our symbols correct. There are nounits having the symbols: 'mw' or 'kwh'! Presumably, you are either trying to express a 'milliwatt' (mW) or a 'megawatt' (MW), and a kilowatt hour (kW.h)?You cannot convert either milliwatts or megawatts into kilowatt hours, as they measure completely different quantities!The milliwatt and the megawatt both measure power(not 'electricity'!). The kilowatt measures energy(which is not a 'rate of consumption'!).
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!
How many MW is 25KW?
1 kw = 0.001 mw 25 kw = 0.025 mw
How do you convert mw to mva?
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.
What does mva mean in electrical terms?
MVA is the apparent power. MVA=( MW+ MVAr)1/2
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
A transmission line has 30 mw and 40 mvar flowing what is the mva flow on the circuit?
MVA= square root of (MW2 + MVAR2 )
How many mega volt ampere are there in a 1 mega watt generator?
MVA(Mega volt ampere) is the cos component of MW. So one should know the power factor of the system for conversion from MVA to 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
How is a 100 MVA transformer cooled?
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.
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 )
How do you convert AM to MW?
100 mW to W
Why DAM capacity in MW and generator in MVA?
Easy, you don't sell MVAh, you sell MWh. MVA is used in rating generators because it combines Watts and vars. MW is used to let you know what kind of money you can make, since you also are probably wanting to produce vars in order to support your grid.
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.
