Three-Phase Power Calculator

In industrial and commercial electrical systems, three-phase power is the standard for efficient energy transmission and heavy machinery operation. This calculator helps you determine the key power metrics required for system sizing, link budgeting, and efficiency analysis.

Key Calculations Explained

  • Real Power (P): Measured in kilowatts (kW), this is the “working” power that actually performs the work (e.g., turning a motor).
  • Apparent Power (S): Measured in kilovolt-amperes (kVA), this is the total power supplied to the system, including the power required to create magnetic fields.
  • Reactive Power (Q): Measured in kilovolt-amperes reactive (kVAR), this represents the power that bounces back and forth between the source and the load without performing work.

Power Calculations

*Real Power $P = \sqrt{3} \times V_L \times I_L \times PF$. Apparent Power $S = \sqrt{3} \times V_L \times I_L$.
