Q: How do you convert kVA to kW?

kW = kVA × power factor . For example, a 100kVA transformer feeding a load at power factor 0.9 can supply 90kW of real power. At power factor 1.0, kVA and kW are equal.

Q: How do you convert kW to kVA?

kVA = kW ÷ power factor . A 90kW load at power factor 0.9 represents 100kVA of apparent power. Generators and transformers are rated in kVA because they must supply both real and reactive power.

Q: What power factor should I use?

Typical values: 1.0 for resistive loads (heating, lighting filament), 0.95 for modern LED lighting, 0.85 for typical motors, and 0.7–0.8 for older or lightly-loaded motors. A power factor below 0.8 usually warrants correction.

Question 1

How do you convert kVA to kW?

Accepted Answer

kW = kVA × power factor. For example, a 100kVA transformer feeding a load at power factor 0.9 can supply 90kW of real power. At power factor 1.0, kVA and kW are equal.

Question 2

How do you convert kW to kVA?

Accepted Answer

kVA = kW ÷ power factor. A 90kW load at power factor 0.9 represents 100kVA of apparent power. Generators and transformers are rated in kVA because they must supply both real and reactive power.

Question 3

What is kVAR?

Accepted Answer

kVAR (reactive power) is the power that flows back and forth to energise the magnetic fields of motors and transformers without doing useful work. It is found from the power triangle: kVAR = √(kVA² − kW²). Power factor correction reduces kVAR.

Question 4

What power factor should I use?

Accepted Answer

Typical values: 1.0 for resistive loads (heating, lighting filament), 0.95 for modern LED lighting, 0.85 for typical motors, and 0.7–0.8 for older or lightly-loaded motors. A power factor below 0.8 usually warrants correction.
