Convert Kilovolt-amps (KVA) to Volt-amps (VA)
To convert KVA to VA , Please provide the values below:
To calculate KVA to VA , use the following formula:
The Real Power in Wattsis equal to the Apparent Power in Volt-amps multiplied by the Power factor (pf)
For example,
If an Induction motor takes 10KVA power at 0.95 (lag) power factor from the AC source. Calculate the VA rating of the motor.
Answer
Where,
Power S = 10KVA , Pf = 0.95
S (VA) = SKVA x 1000
S (VA) = 10 x 1000
S (VA) =10000
VA = 10000
For example,
If an Induction motor takes 1KVA power at 0.95 (lag) power factor from the AC source. Calculate the VA rating of the motor.
Answer
Where,
Power S = 1KVA , Pf = 0.95
S (VA) = SKVA x 1000
S (VA) = 1 x 1000
S (VA) =1000
VA = 1000

Frequently Asked Questions:
What do you convert watts to volt-amps for ?
When you calculate equipment loads, fuses and wire sizes, you convert watts to VA and device capacity is written in KVA, so KVA are converted to VA.
What is DC Circuit 1 KVA in volt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 1KVA is the equivalent of 1000VA.
What is AC Circuit 5KVA in volt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 5KVA is the equivalent of 5000VA. This equivalence means that the power factor of that power supply is 0.85.
What is the formula for Kilovolt-amps to VA?
Volt-amps (VA) = KiloVolt-Amps (KVA) X 1000.
