mw is the unit of real power and mvar is unit of reactive power. You should now the current and power factor angle to calculate the voltage.
p=vi cos pi
q=vi sin pi
AnswerI think you mean MW, not mw -capital 'M' mega; lower-case 'm' milli!!! And the symbol for watt is a capital 'W', not a lower case 'w'. Also, I think you mean 'Mvar'(mega, not milli!).

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 voltage of French national grid?
The voltage of the French National Grid is 2000 mw high voltage. It is a direct current electrical interconnector between the British and French transmission.
Full fom of MVAR?
Mega - Volt - Ampere - Reactive
How many MW is 25KW?
1 kw = 0.001 mw 25 kw = 0.025 mw
How do you find power in parallel circuit?
Voltage will be same in all branches. Voltage= Current * Total Resistance
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 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 does mva mean in electrical terms?
MVA is the apparent power. MVA=( MW+ MVAr)1/2
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 do you find the current rating of a zener diode if the power rating is 500mw and a voltage rating of 10v?
A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
Is mw and mW the same in watts . is it the same or is mW stronger voltage then mw?
The units mw and mW are the same. They mean milliwatts. The terms Mw and MW, however, means megawats, which is a billion (1x109) times greater than a mw or a mW.Another AnswerThe correct symbol for a watt is an upper-case 'W'. So the correct symbol for a milliwatt is 'mW' (not 'mw'), and the correct symbol for a megawatt is 'MW' (not 'Mw').
How does surge impedance effect on transmittion line?
The SIL=(KV LL / Zo), where the V(LL) is the receiving end voltage in kV and Zo is the surge impedance in ohms. when the line is loaded over its SIL, it behaves like a shunt reactor - absorbing Mvar from the system, and when is loaded less its SIL it behaves like a shunt capacitor, supply Mvar back to the system. So to increase the Surge Impedance Loading (SIL), we need to decrease the the surge impedance of the line, and that can be done by introducing series capacitors (capacitors in series with the transmission line) or shunt capacitors (capacitors in parallel with transmission lines), which means providing Mvar to the system and reducing the Mw. hopefully that helps
How many watts are in 5 volts?
It's important to use the correct symbols for units of measurement. There is no such symbol as 'mw' -so you either mean 'mW' (milliwatts) or 'MW' (megawatts), which are significantly different! The watt is the SI unit for power. Voltage (potential difference) is measured in volts. Power and voltage are two completely different quantities, so it doesn't make sense to ask 'How much voltage is 5 mW (or 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 percentage of energy in the US is from windmills?
Global leaders in installed wind energy are Germany at 23,300 MW; US at 20,413 MW; Spain at 15,900 MW; China at 9,000 MW; and India at 8,757 MW. If you find the total energy used in the US then you will have your percentage.
