Fill in any two of inductance L, rated current I and reactive power Q — the third is derived. The phase basis (single / three-phase) must be chosen, because the two bases differ by exactly a factor of three.
X = 2πfL · U_L = I·X · Q₁ = I²X (single-phase) · Q₃ = 3I²X (three-phase)
Still required to complete the calculation: inductance L, rated current I, reactive power Q.
L = 1 mH, I = 150 A, f = 50 Hz → X = 0.3142 Ω, U_L = 47.12 V, single-phase Q₁ = 7.07 kvar, three-phase Q₃ = 21.21 kvar.
Single-phase and three-phase differ by exactly a factor of three — always state which basis a kvar figure is quoted on.
The product library (quote-data) carries no per-model inductance or rated current, so no value is auto-filled for a model; the actual figures are confirmed on the factory parameter sheet. An em dash means the value is unavailable — it is never rendered as zero.
