Power Factor Correction Guides for Plant Engineers
These guides come from the engineers at Saudi Power Factor Company. Each one answers a single question first, then shows the working: a table, a checklist or an example with numbers. The articles are written by Eng. Ahmed Ali.

Bills, penalties and targets
- Power factor penalty calculation: Saudi bill example. Follow the figures on a bill from the charge back to the kVAr you need.
- Target power factor in Saudi Arabia: is 0.9 or 0.95 right? Compare the two targets and the effect of each on sizing.
- Power factor correction cost in Saudi Arabia: factors. The inputs that move a price, and what to send to fix it.
- Power factor correction ROI payback: how to calculate. A method for turning a bill and a quotation into a payback period.
Sizing and choosing equipment
- Capacitor bank sizing calculation: kVAr formula and example. The formula, the inputs and a worked case.
- APFC vs fixed capacitor bank: how to choose for your load. When one steady load justifies a fixed bank, and when it does not.
- Detuned vs standard capacitor bank: which one you need. A decision guide for sites with drives and electronic loads.
- IEC 61921 APFC panel: what the standard means for you. Which parts of the standard to ask a supplier about.
Harmonics, surveys and upkeep
- VFD harmonics and power factor: what engineers should know. Why drives change the capacitor choice.
- Power quality survey report: what you should receive. The sections and measurements a complete report contains.
- Capacitor bank maintenance checklist for plant engineers. The inspections to schedule, and how often.
- Seven capacitor bank replacement signs plants should check. Symptoms that show a bank is near the end of its life.
Need a quotation instead of a guide?
If you already know what you need, go straight to APFC panels, the power quality survey or the full power factor correction in Saudi Arabia overview. Otherwise request a quotation and send your bill.
