GGSTech ToolsHow this calculator works
Required capacitor kVAR ≈ kW × [tan(cos⁻¹ PF1) − tan(cos⁻¹ PF2)].
Example: 100 kW from PF 0.75 to 0.95 requires roughly 55 kVAR.
Practical guidance
This tool is designed for fast planning and learning. Enter realistic values and compare the result with nameplate data, local standards and engineering practice before making a final selection.
Frequently asked questions
Should I target 1.00 PF?
Usually no. A slightly lower target such as 0.95–0.99 is commonly selected to avoid leading PF and overcompensation.
Can harmonics affect capacitor selection?
Yes. Harmonic-rich systems may require detuned reactors or other harmonic mitigation.
