Power factor correction planning

A workflow guide for using power-factor correction estimates without turning the result into selected correction equipment.

Planning purpose

Power-factor correction planning starts with an estimate, not a product choice. The correction calculator can estimate kVAr from entered kW, existing PF and target PF. It does not check harmonics, switching steps, resonance, site operating profile or equipment suitability.

Use the result to decide whether a more detailed correction study or supplier discussion is needed.

Workflow

  1. Confirm the real power basis in kW.
  2. Record the existing power factor and source.
  3. Record why the target power factor is being used.
  4. Estimate correction kVAr.
  5. Stop before product selection and review harmonics, switching, duty profile and network requirements.

Boundaries

  • Do not present estimated kVAr as selected equipment.
  • Do not use a generic target PF without knowing why that target applies.
  • Do not ignore harmonics, resonance, switching or load profile.
  • Do not describe the estimate as a network-approved solution.

Questions

Is a low power factor always fixed with a capacitor?

No. The calculator can estimate kVAr, but equipment choice, harmonics, switching, network rules and manufacturer advice still need engineering review.

Can the calculator choose target PF?

No. The target must come from the project, commercial requirement, network context or engineering review.
