Three Phase Power Formula:
| From: | To: |
The three phase power formula calculates kilowatts from current, voltage, and power factor in a three phase electrical system. It provides an accurate measurement of real power consumption in industrial and commercial applications.
The calculator uses the three phase power formula:
Where:
Explanation: The formula accounts for the three-phase nature of the electrical system, converting the apparent power to real power in kilowatts.
Details: Accurate power calculation is crucial for electrical system design, load balancing, energy consumption monitoring, and determining equipment requirements in three-phase systems.
Tips: Enter current in amps, voltage in volts, and power factor (between 0 and 1). All values must be valid positive numbers.
Q1: What is power factor and why is it important?
A: Power factor represents the ratio of real power to apparent power. It's important because it affects the efficiency of power delivery and can impact electricity costs.
Q2: What is the typical range for power factor?
A: Power factor typically ranges from 0 to 1, with 1 being ideal. Most industrial systems operate between 0.8-0.95.
Q3: When is this calculation most useful?
A: This calculation is essential for industrial electricians, engineers, and facility managers working with three-phase motors, generators, and power distribution systems.
Q4: Are there limitations to this formula?
A: This formula assumes balanced three-phase loads and may not be accurate for unbalanced systems or systems with significant harmonic distortion.
Q5: How does this differ from single-phase power calculation?
A: Three-phase systems use the √3 factor (approximately 1.732) while single-phase systems do not, making three-phase more efficient for power transmission.
