Calculation of power factor correction

The correct calculation of a power factor correction systems depends on the electrical power consumption. Our easy to use calculation tool helps you determine the correct compensation power. All you need is the electrical utility bill from your electrical power company or the data of your inductive loads.

An optimally designed power factor correction equipment saves money and increases the utilization of the electrical infrastructure.

Also available as an Android-APP in the Google Play App Store (CAPAG).

Utility bill invoicing period -
High tariff
Average cos(φ) HT (High tariff, inductive)
Compensation power HT inductive (High tariff) with real power maximum and safety margin [kvar]
Average cos(φ) HT (High tariff, capacitive)
Compensation power HT capacitive (High tariff) with real power maximum and safety margin [kvar]
Maximum power in high tariff [kW]
Low tariff
Average cos(φ) LT (Low tariff, inductive)
Compensation power LT inductive (Low tariff) with real power maximum and safety margin [kvar]
Average cos(φ) LT (Low tariff, capacitive)
Compensation power LT capacitive (Low tariff) with real power maximum and safety margin [kvar]
Maximum power in low tariff [kW]
We recommend to install a PFC system with following power [kvar]
Attention! Due to the capacitive reactive power, an electronic power factor compensation must be used.
Your yearly cost savings [CHF]
Apparent current without compensation per phase [A]
Apparent current with compensation per phase [A]
Reduction of apparent current per phase [A]
Reduction of apparent current in percent per phase [%]
Advantages of power factor correction:
  • Reduction of energy cost
  • Reduction of environmental damage and CO2 emission
  • Reduction of apparent current leads to higher grid efficiency.
  • Reduction of thermal stress on insulation and electrical systems
