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).---

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.
How do you define the synchronous generator capability limiters?
SYNCHRONOUS GENERATOR CAPABILITY LIMITTsynchronous generator capability limiters are as follows 1.MVA or armature current limit of generator: this depends on the cooling system of generator so that temperature rise in generator is limited to safe value.depending on cooling system effectiveness and temperature limit for the insulation used in generator, MVA limit is decided.2.MW limit: this is determined by the power output capacity of prime mover to which generator is connected.3.rotor angle limit: this is related to stability of generator which is synchronised to the grid.ideally this could be 90 degree, but in practice this is limited to70 degree so as to have better stability margin in transient and dynamic condition.the generator falls out of synchronism in trasient condition if rotor angle is close to 90 degree.4. rotor current limit: the field winding placed on rotor has got limited current carrying capacity, beyond which it may burn .so this limit is used.all these limitters make capability curve of g generator within which the generators operates safelyr. k.niranjanemail id: rkniranjan@yahoo.com
What does mva mean in electrical terms?
MVA is the apparent power. MVA=( MW+ MVAr)1/2
What is mva?
In electrical engineering it can be millivolt amperes, unless it's MVA then it is megavolt amperes. Such as in the use of large transformers.
A transmission line has 30 mw and 40 mvar flowing what is the mva flow on the circuit?
MVA= square root of (MW2 + MVAR2 )
What does the medical abbreviation MVA mean?
MVA often stands for Motor Vehicle Accident. It may also stand for manual vacuum aspiration.
What does the acronym mva stand for?
Like many acronyms, MVA can stand for many different things. The most common use refers to a motor vehicle accident, however, there are more than 100 other uses for MVA including many organizations, different pieces of machinery or equipment and even legal terms.

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

What kind of power is MVA?
MVA is the aparant power.
When was MVA in Asia created?
MVA in Asia was created in 1968.
What is the population of MVA in Asia?
MVA in Asia's population is 500.
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.
What are the 3 important things necessary for generating?
Three important things for generating are to consider the following: Voltage Level, Frequency and the load in terms of Amprere or MVA i.e. capacity of the Generator
Is the Maryland MVA opened on weekends?
can u get a i.d card on Saturday at the Maryland mva
