Your project criterion: enter the value from your governing code, specification or approved supplier data. No standard value is assumed.
Engineering Assumptions
Direct calculation — Capacitor power-factor correction
- The target power factor is user-entered from the utility requirement or the project's governing code.
- All percentages and inputs are user-defined; the calculation is purely arithmetic and assumes no particular code or specification.
Formula Summary
- PF_existing = P ÷ S
- kVAR_required = P × (tan(φ1) − tan(φ2))
Results
Enter your data and press Calculate to see the results.
Engineering Insight
Pushing the target power factor closer to 1 raises the required capacitor bank size non-linearly.
Recommended Action
Verify thermal and harmonics compatibility before installing the computed capacitor bank.
