Convert kilowatts (KW) to volt-Amps (VA)
To convert KW to VA , Please provide the values below:
To calculate kilowatts to kilovolt-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 01
If an Induction motor takes 10KW active power at 0.8 (lag) power factor from the AC source. Calculate the VA rating of the motor.
Answer
Where,
Active power P = 10KW , Pf = 0.8
We Know
S (VA) = 1000 x Pkw ÷ Pf
S (VA) = 1000 x 10 ÷0.8
S (VA) = 12500
VA = 12500
For Example 02
If an Induction motor takes 8KW active power at 0.95 (lag) power factor from the AC source. Calculate the VA rating of the motor.
Answer
Where,
Active power P = 8KW , Pf = 0.95
We Know
S (VA) = 1000 x Pkw ÷ Pf
S (VA) = 1000 x 8 ÷ 0.95
S (VA) = 8421
VA = 8421

Frequently Asked Questions:
What do you convert kw to volt-amps for ?
When you calculate equipment loads, fuses and wire sizes, you convert watts to VA and device capacity is written in VA, so kilo watts are converted to VA.
What is DC Circuit 1 kw in kilovolt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 1 kilo watt is the equivalent of 1000 VA.
What is AC Circuit 10 kilo watts in kilovolt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 10 watts is the equivalent of 12500 VA. This equivalence means that the power factor of that power supply is 0.8.
What is the formula for kilo watts to volt-amps ?
Apparent Power(VA) = 1000 x Real Power(KW) / Power factor in PF.
