Power Factor vs Real Power (P)

Vedi formula →

Formula

## Power Factor Power factor indicates how effectively electrical power is being converted to useful work. ### Formulas **PF = P / S = kW / kVA** **Q = sqrt(S^2 - P^2)** A power factor of 1.0 means all power is real (useful). Low power factor means more current flows than needed, increasing losses. Industrial facilities typically aim for PF > 0.95 to avoid utility penalties.

Esempio Risolto

A facility drawing 30 kVA with 25 kW real power.

  1. 01PF = 25 / 30 = 0.833
  2. 02Q = sqrt(30^2 - 25^2) = sqrt(900 - 625) = sqrt(275) = 16.58 kVAR
  3. 03Phase angle = arccos(0.833) = 33.6 degrees
