Power Factor Correction
Raising the power factor by supplying the reactive power of inductive loads from capacitors — avoids reactive-energy penalties and reduces line current and losses.

- Reactive power before / after
- 88.2 / 14.2 kVAr
- Apparent power before / after
- 133.3 / 101.0 kVA
- Line current before / after
- 192.5 / 145.8 A
- Current reduction
- 24 %
- Capacitance per phase (delta)
- 490.3 µF
- Capacitance per phase (star)
- 1,471 µF
- Inductive reactive / active ratio (after)
- 14 %
- Q/P = 14 % — Turkish tariff limit for inductive energy is 20 %
METHOD
How it is calculated
Q_c = P · (tan φ₁ − tan φ₂) C_Δ = Q_c / (3 · 2πf · U²) C_Y = 3 · C_Δ
ASSUMPTIONS & NOTES
- In Türkiye the inductive reactive / active energy ratio must stay below 20 % and the capacitive ratio below 15 %, i.e. cos φ ≈ 0.98.
- Use detuned (reactor-filtered) banks where harmonics are present to avoid resonance.
Results are for preliminary design and checking; base the final design on the governing standard and safety factors.
