Formula variables
- Existing power factor is the starting PF condition.
- Target power factor is the planned corrected PF condition.
- Corrected current ratio compares after-current to before-current for the same kW.
- Current reduction is a screening estimate before equipment and utility review.
Assumptions
- The comparison assumes the same kW load and voltage before and after correction.
- Current changes in inverse proportion to power factor for the same real power.
- The result is a ratio screen, not a capacitor-bank or harmonic study.
- This calculator does not design correction equipment, switchgear, detuning reactors, or utility tariff treatment.
Examples
0.75 to 0.95 PF. Improving from 0.75 to 0.95 PF gives an estimated corrected-current ratio of 0.789 and about 21.05 percent current reduction.
Correction workflow. Use this ratio with kVAR, bill-impact, and manufacturer equipment review rather than treating it as a correction design.
