Power Factor Correction Calculator
Estimate capacitive reactive power compensation from real power and a target power factor.
Power Factor Correction Calculator User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- For a 10 kW load, estimate the required kvar and current reduction when improving power factor from 0.7 to 0.95.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Required compensation is P×[tan(arccos(initial PF))-tan(arccos(target PF))].
scope of use
Assumes sinusoidal inductive loads with lagging power factor. Capacitor wiring and switching are not designed; real installations require qualified professionals.
