What else can I help you with?
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 the cost of Static Var compensator?
For 230 kv application, Its around 75k/MVar
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 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
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).
Full fom of MVAR?
Mega - Volt - Ampere - Reactive
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 )
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 cost of Static Var compensator?
For 230 kv application, Its around 75k/MVar
What does mva mean in electrical terms?
MVA is the apparent power. MVA=( MW+ MVAr)1/2
How do find voltage from mvar and mw?
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 piq=vi sin piAnswerI 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!).

What is full form of mvar?
As you have written it (mvar), it stands for 'reactive millivolt amperes', but I think you probably mean 'Mvar', which stands for 'reactive megavolt amperes'. These are units for reactive power of an alternating-current load.A lower-case 'm' represents 'milli', whereas an upper-case 'M' represents 'mega'. 'V' represents 'volts', 'A' represents 'amperes', and 'r' represents 'reactive'.SI does not specify a symbol for reactive volt amperes (it only recognises 'watts'), so it is seen in written in various ways, including: var, VAR, VAr, VA(r), and VAr -in each case, it is also common to see a 'raised period' between the V and the A -e.g. V.Ar .
What is the formula for calculate 3 phase power MVAR?
Q = 3 Vph Iph sin(phase angle) = 31/2 Vline Iline sin(phase angle)
How you convert Amps into MVA?
1mva = 1000kva so you simply divide by 1000. 10000KVA = 10MVA K = kilo = 1000 M = mega = 1000000
