Convert Volt-amps (VA) to Kilovolt-amps (KVA)
To convert VA to KVA,Please provide the values below:
To calculate watts to volt-amps , 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 100VA power at 0.95 (lag) power factor from the AC source. Calculate the KVA rating of the motor.
Answer
Where,
Power S = 100VA , Pf = 0.95
S (KVA) = SVA ÷ 1000
S (KVA) = 100 ÷ 1000
S (KVA) =0.1
KVA = 0.1
For example,
If an Induction motor takes 8000VA power at 0.85 (lag) power factor from the AC source. Calculate the KVA rating of the motor.
Answer
Where,
Power S = 8000VA , Pf = 0.85
S (KVA) = SVA ÷ 1000
S (KVA) = 8000 ÷ 1000
S (KVA) =8
KVA = 8

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 VA are converted to KVA.
What is DC Circuit 1000 VA in volt-amps (KVA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 1000VA is the equivalent of 1 KVA.
What is AC Circuit 5000VA in volt-amps (KVA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 5000VA is the equivalent of 5 KVA. This equivalence means that the power factor of that power supply is 0.85.
What is the formula for VA to Kilovolt-amps ?
Kilovolt-amps (KVA) = Volt-Amps (VA) / 1000.
