Three Phase Power Calculator
Calculate three phase electrical power
About this calculator
A three phase power calculator determines the electrical power consumption in three-phase systems commonly used in industrial and commercial applications. This tool helps engineers, electricians, and facility managers calculate real power, apparent power, and reactive power using voltage, current, and power factor values. Understanding three-phase power calculations is essential for proper electrical system design, energy management, and cost optimization in facilities with heavy machinery and equipment.
How to use
Enter the line voltage, line current, and power factor values into the calculator. Select whether you're calculating for a wye or delta configuration. The calculator will instantly compute real power (watts), apparent power (VA), and reactive power (VAR) for your three-phase electrical system.
Frequently asked questions
What's the difference between single-phase and three-phase power?
Three-phase power uses three alternating currents with 120-degree phase differences, providing more efficient power transmission and smoother operation for large motors and industrial equipment.
How do I measure power factor in three-phase systems?
Power factor is measured using a power quality analyzer or calculated by dividing real power by apparent power. It indicates system efficiency.
What are wye and delta configurations?
Wye configuration connects phases in a star pattern with a neutral point, while delta connects phases in a triangle without neutral.
