Frequently asked questions

How do I convert kW to amps in three-phase?

For three-phase: I (A) = (kW × 1000) ÷ (√3 × VLL × power factor). For 400 V three-phase at unity power factor, 1 kW ≈ 1.44 A.

How do I convert kVA to kW?

kW = kVA × power factor. A 100 kVA load at 0.9 power factor delivers 90 kW of real power and 43.6 kvar of reactive power.

What is the difference between kW, kVA and kvar?

kW is real power consumed by the load, kVA is apparent power drawn from the supply, and kvar is reactive power that circulates between source and load. They form a right triangle: kVA² = kW² + kvar².
