How to convert apparent power in kilovolt-amps (kVA) to real power in watts (W).
The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), times the power factor PF:
P(W) = 1000 × S(kVA) × PF
So The watts are equal to 1000 times kilovolt-amps times the power factor.
watts = 1000 × kilovolt-amps × PF
or
W = 1000 × kVA × PF
What is the real power in watts when the apparent power is 3 kVA and the power factor is 0.9?
Solution:
P = 1000 × 3kVA × 0.9 = 2700W
What is the real power in watts when the apparent power is 5 kVA and the power factor is 0.9?
Solution:
P = 1000 × 5kVA × 0.9 = 4500W
What is the real power in watts when the apparent power is 8 kVA and the power factor is 0.9?
Solution:
P = 1000 × 8kVA × 0.9 = 7200W
What is the real power in watts when the apparent power is 10 kVA and the power factor is 0.9?
Solution:
P = 1000 × 10kVA × 0.9 = 9000W
What is the real power in watts when the apparent power is 50 kVA and the power factor is 0.9?
Solution:
P = 1000 × 50kVA × 0.9 = 45000W
