Three Phase Power Calculator
Calculate power, current, and voltage in three-phase electrical systems with power factor correction
About this calculator
The Three Phase Power Calculator is an essential tool for electrical engineers, technicians, and students working with three-phase electrical systems. It accurately calculates power (kW), current (amperes), and voltage relationships in balanced three-phase circuits while accounting for power factor correction. This calculator simplifies complex electrical calculations, ensuring proper system design, load analysis, and energy efficiency optimization in industrial and commercial electrical installations.
How to use
Enter any two known values from voltage (line-to-line or line-to-neutral), current, power, and power factor. Select the appropriate voltage type and calculation method. The calculator will automatically compute the missing electrical parameters using standard three-phase formulas, providing instant results for your electrical system analysis.
Frequently asked questions
What is power factor in three-phase systems?
Power factor is the ratio of real power to apparent power, indicating how efficiently electrical power is used in the system.
What's the difference between line and phase voltage?
Line voltage is measured between two phases, while phase voltage is measured between one phase and neutral in a wye connection.
Why use three-phase power over single-phase?
Three-phase systems provide more efficient power transmission, better power balance, and reduced conductor material requirements for the same power output.
