Power Factor Calculator
Power Factor Calculator: The power factor is a measure of how effectively electrical power is being converted into useful work output. It is defined as the ratio of real power (kW) to apparent power (kVA) in a circuit. A power factor of 1 indicates that all the energy supplied by the source is being used effectively, while a lower power factor indicates inefficiencies.

What is Power Factor?
Power factor is a critical concept in electrical engineering, defined as the ratio of real power (measured in kilowatts, kW) to apparent power (measured in kilovolt-amperes, kVA). It indicates how effectively electrical power is being converted into useful work output. A power factor of 1 (unity) signifies that all the energy supplied is being used effectively, while lower values indicate inefficiencies that can lead to increased energy costs and equipment strain.
What is a Power Factor Calculator Website?
A Power Factor Calculator website is an online tool designed to help users calculate various electrical parameters related to power factor, including real power, apparent power, reactive power, and the necessary correction capacitor values for both single-phase and three-phase circuits. This tool is particularly useful for electrical engineers and technicians in optimizing electrical systems for better efficiency and cost-effectiveness.

Formula of Power Factor Calculator
Single Phase
- Power Factor (PF) = $$ \frac{P(kW)}{V(V) \times I(A)} $$
- Apparent Power (S) = $$ \frac{V(V) \times I(A)}{1000} $$
- Reactive Power (Q) = $$ \sqrt{S(kVA)^2 - P(kW)^2} $$
Three Phase
- Power Factor (PF) = $$ \frac{P(kW)}{\sqrt{3} \times V_{L-L}(V) \times I(A)} $$
- Apparent Power (S) = $$ \frac{\sqrt{3} \times V_{L-L}(V) \times I(A)}{1000} $$
- Reactive Power (Q) = $$ \sqrt{S(kVA)^2 - P(kW)^2} $$
