How this service works
Capacitor kVAR needed to raise power factor from one value to another, with new kVA and current and capacitance per phase.
Output
Returns the required capacitor bank size in kVAR, kVA and kVAR figures before and after correction, percentage and absolute kVA reduction, line current before and after, and (when voltage is supplied) wye and delta capacitance per phase in microfarads, plus echo of inputs and a disclaimer.
Example use cases
Industrial facility power factor penalty avoidance
“Our factory has a 200 kW motor load running at 0.72 power factor on a 415V 50Hz three-phase supply and the utility is charging us a penalty — how many kVAR of capacitors do we need to install to bring the power factor up to 0.95, and what's the per-phase capacitance for wye connection?”
Data center UPS sizing after correction
“We have a 350 kW data center load at 0.80 power factor on 480V 60Hz — calculate the kVAR capacitor bank needed to correct to 0.99, and tell me the new kVA demand so I can rightsize our UPS and transformer.”
Commercial building energy audit
“I'm auditing a 75 kW commercial HVAC system running at 0.85 power factor — show me the capacitor kVAR required to reach 0.95, the reduction in kVA, and the new line current at 208V 60Hz.”
Technical details
Endpoint
GEThttps://electrical-calc.x402tookit.com/power-factor-correction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to size a capacitor bank to correct a lagging power factor for a known real power load, especially when you also need per-phase capacitance values for three-phase wye or delta installations. Prefer this over general three-phase calculators when power factor correction — not just load analysis — is the primary goal.
Side effects
- Missing required parameters (kw, pfFrom, pfTo) returns error
- pfTo not greater than pfFrom returns invalid input
- Power factor values outside (0, 1] return validation error
- voltageV required for current and capacitance outputs — omitting it yields null for those fields
- Frequency defaults to 60 Hz if omitted; incorrect frequency produces wrong capacitance values
- Non-numeric parameter values return parse error
