Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.

You have 240volts and a load of 50 amps what is the kva?
A voltage of 240 volts is not a common three phase voltage. Single phase kva of 240 voltas and 50 amps is I x E/1000 = 240 x 50 = 12000/1000 = 12 kVa -- Assuming the 240 volts is phase to phase voltage, and this is a three phase application: KVA = V*I*sqrt (3) = 20.78KVA
How many ampere in 694 kVA?
It depends on the voltage and whether it is a single- or three-phase load.
What is the rating of circuit breaker needed for a 500kva load?
To answer this question a voltage needs to be stated and whether the load is three phase or single phase. Without the voltage the amperage can not be calculated. For single phase, Amps = kva x 1000/voltage, for three phase, Amps = kva x 1000/1.73 x voltage.
How to convert 100ampere to kva?
Divide by your number of phases 1 or 3 then divide by your Voltage. If its a 3 phase supply Voltage you need to divide by your 3 phase voltage for balanced loads and by your single phase voltage for unbalanced loads requiring a neutral.
Is 10 kva supply to 3 phase load is equal to 10kva supply to single phase load?
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
Convert 2KW to KVA in single phase?
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
How do you calcualte from ampere to kva?
For single phase,kva=voltage(volts)xcurrent(amps)/1000 For,three phase,kva=1.732xvoltsxamps/1000
What are the equations to get KVA?
If using L-L voltages, the three phase power = V*I*sqrt(3)If using L-N voltages, the single phase power = V*ITo convert single phase to three phase, multiply by 3.
What is the equivalent to135A single phase at three phase 208V?
135 A at 120 v single-phase is 16.2 kVA. With a 208 v three-phase supply you get three single-phase 120 v supplies, so the same kVA is produced with a balanced load of 45 amps on each phase.
How many amperes in kva?
It depends on the voltage and whether it is a single- or three-phase load.
How do you convert kva to amps three phase system when you have 220-240 volts?
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
How can you convert the kva rating into kw rating?
kva*cos(phase angle)
