Power factor correction
Enter load and system values to estimate the required capacitive compensation.
Method and boundaries
Qc = P [tan(acos pf₁) − tan(acos pf₂)]. Single: C = Qc/(2πfV²); delta: C = Qc/(6πfVLL²); star: C = Qc/(2πfVLL²).
Estimate for a lagging inductive load only. Resonance, harmonics, switching stages, protection, equipment suitability, and code compliance are not evaluated.
Method and boundaries
Qc = P[tan(acos pf₁) − tan(acos pf₂)]. Per-branch capacitance depends on single-phase, delta, or star connection; three-phase input voltage is line-to-line voltage.
Resonance, harmonics, switching stages, protection, equipment suitability, and code compliance are not evaluated. SRC-004 · model 1.0.0 · user-input-v1.
