Power Factor from kW/kVA Calculator

Calculate power factor PF = P(kW)/S(kVA) = cosφ. Find reactive power Q = √(S²-P²) kVAR. Displacement power factor vs total PF including harmonics. True PF from power analyzer measurements.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)

How It Works

Calculate power factor PF = P(kW)/S(kVA) = cosφ. Find reactive power Q = √(S²-P²) kVAR. Displacement power factor vs total PF including harmonics. True PF from power analyzer measurements

Each component has a specific meaning:

  • Power analyzer measurements — The power analyzer measurements recorded for the patient or scenario being assessed.

Note: Interpret the pf from kw/kva result against the clinical thresholds and context described above.

How to Use

Enter the power analyzer measurements for the patient or scenario you are assessing. Calculate power factor PF = P(kW)/S(kVA) = cosφ. Find reactive power Q = √(S²-P²) kVAR. Displacement power factor vs total PF including harmonics. True PF from power analyzer measurements. Use the pf from kw/kva result to inform your clinical assessment.
