Как преобразовать кВт в кВА?

Разделите the real power in kW на the power factor: kVA = kW ÷ PF. For example, 80 kW at 0.8 PF = 80 ÷ 0.8 = 100 kVA.

Only when power factor equals 1 (purely resistive load). In most real-world applications, kVA is greater than kW because power factor is less than 1.

kVAS = P ÷ PF

Where:
S = Apparent Мощность (kVA)
P = Real Мощность (kW)
PF = Мощность Factor

Краткая справка (PF=0.8)

kW	kVA
10 kW	12.5 kVA
25 kW	31.25 kVA
50 kW	62.5 kVA
100 kW	125 kVA

Understanding kW to kVA Conversion

kW (kilowatts) measures real power—the actual power consumed to do work. kVA (kilovolt-amperes) measures apparent power—the total power supplied to a circuit including reactive power.

The Мощность Треугольник

In AC circuits, apparent power (kVA), real power (kW), and reactive power (kVAR) form a triangle. The power factor is the ratio of real to apparent power: PF = kW ÷ kVA.

Why кВА Matters

Transformers and generators are rated in kVA because they must handle the total current regardless of how efficiently it's used. A lower power factor means more kVA is needed for the same kW.
