Power Factor Correction Calculation

Calculation of the energy savings

In order to calculate power factor correction for your installation, your should follow the steps below:

Step 1 – Calculate Actual Load (kW)

(Load) Power kW = Volts V x √3 x Current I x Power factor Pf

Step 2 – Calculate Required Power Factor Correction (kVAr)

Power Factor Correction kVAr = Power kW (TanΦi – TanΦd)

Φi = Cos-1 Initial Power Factor Pf
Φd = Cos-1 Required Power Factor Pf

Step 3 – Calculate Actual Power Factor Correction [kAVrl

Actual Power Factor Correction Pf = Cos (Tan-1 (TanΦiCorrection kVAr/Power kW ))

Typical Power Factor Correction available in multiples of 25kVAR’s, for further details please Contact Blakley Electrics Technical Department.

At the end of the spreadsheet you will get the calculation of the energy savings for above power factor correction.

  1. Initial Current (Amps)
  2. Original Load (kVA)
  3. Corrected Current (Amps)
  4. Corrected Load (kVA)
  5. Reduction in Current (Amps)
  6. Reduction in Load (kVA)
  7. Annual CO2 Savings ( kg C02)
