Power Factor Calculator
This website provides a Power Factor calculator for both single-phase and three-phase electrical systems. Use this tool to calculate power factor, apparent power, reactive power, and to determine the required capacitance for power factor correction.
What is Power Factor?
Power Factor is a measure of how effectively electrical power is being used. It is defined as the ratio of real power, which performs useful work, to apparent power, which is the product of the current and voltage supplied to the circuit. A Power Factor close to 1 indicates efficient utilization of electrical power.
How to Use
Select the phase type, input the required electrical parameters, and the calculator will provide the results, including power factor, apparent power, reactive power, and capacitor value for correction.

Frequently Asked Questions
Power Factor is the ratio of real power to apparent power in a circuit. It indicates how effectively electrical power is being used.
The calculator computes power factor, apparent power, and reactive power based on the inputs you provide. It also calculates the required capacitance for power factor correction.
A high Power Factor indicates efficient use of electrical power, reducing energy losses and lowering electricity costs.
Apparent Power is the product of current and voltage in a circuit and is measured in kVA (kilovolt-amperes). It represents the total power supplied to a circuit.
Reactive Power is the portion of power that does not perform useful work. It is measured in kVAR (kilovolt-amperes reactive) and is caused by inductive loads such as motors and transformers.
A low Power Factor is typically caused by inductive loads, which require reactive power to create magnetic fields, such as motors, transformers, and fluorescent lighting.
Power Factor can be improved by adding power factor correction capacitors to the electrical system, which provide reactive power and reduce the total current drawn from the power source.
Power Factor Correction involves adding capacitors to an electrical network to counteract inductive loads and improve the Power Factor, reducing energy losses and improving efficiency.
Single-phase power is typically used in residential applications and involves a single alternating current. Three-phase power is used in industrial settings and involves three alternating currents, providing more power and greater efficiency.
Select the appropriate phase type from the dropdown menu before entering your values. The calculator will automatically adjust the input fields based on your selection.
A correction capacitor is used in power factor correction to supply reactive power, reducing the overall current draw and improving the Power Factor of an electrical system.
While basic calculations can be done using this calculator, it is recommended to consult with a qualified electrician or engineer for actual power factor correction in a practical setting to ensure safety and compliance with regulations.
