The 3-Phase Power Calculator is a handy tool designed to help you calculate the power in three-phase electrical systems. Three-phase power is commonly used in industries and large electrical installations because it delivers more efficient and balanced power compared to single-phase systems.

What Is 3-Phase Power?

Three-phase power refers to a type of alternating current (AC) electrical power system that uses three separate currents, each out of phase with the others by 120 degrees. This setup provides constant power transfer and is widely used for heavy machinery, motors, and large power distribution.

How Does the 3-Phase Power Calculator Work?

This calculator helps you find the total power in a three-phase system using key inputs like voltage, current, and power factor. It applies standard formulas to quickly compute the power in watts (W), kilowatts (kW), or megawatts (MW).

How to Use the 3-Phase Power Calculator?

To use the calculator, follow these steps:

  1. Enter the line-to-line voltage (in volts).
  2. Enter the current per phase (in amperes).
  3. Input the power factor (a number between 0 and 1).
  4. Select whether the system is balanced and the type of connection (star or delta).
  5. The calculator will display the total power instantly.

Formulas Used in the Calculator

For balanced three-phase systems, the power can be calculated as:

P = √3 × V × I × Power Factor

Where:

  • P = Power (in watts)
  • V = Line-to-line voltage (in volts)
  • I = Current per phase (in amperes)
  • Power Factor = Ratio of real power to apparent power (between 0 and 1)
