Reactor Inductance ↔ Rating (mH ↔ kvar)

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)

Inputs
Phase basis (required)
Result
Reactance X = 2πfL—
Inductance L—
Rated current I—
Voltage across the reactor U_L = I·X—
Reactive power, single-phase basis: Q₁ = I²X—
Reactive power, three-phase basis: Q₃ = 3I²Xyour basis—

Still required to complete the calculation: inductance L, rated current I, reactive power Q.

Worked example (the customer case)

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.

Insulation level (IEC 60071-1)
Not specified — the factory parameter sheet is required.
Select a rated voltage in the configuration above to see the matching IEC class.
Non-IEC enquiry case:The enquired Um 15 kV / LI 105 kV / AC 52 kV is not an IEC standard combination (no 15 kV and no 105 kV in IEC lists); it belongs to regional systems such as JEC (Japan) / CNS (Taiwan), where a 15 kV class is about LI 95-110 / AC 50-55. Confirm the system before quoting and map to the nearest IEC class (17.5 kV).

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.
