3-Phase Power Formula:
| From: | To: |
3-phase power consumption calculation determines the electrical energy used by a 3-phase motor or system over time. It's essential for energy management, cost estimation, and system efficiency analysis in industrial and commercial applications.
The calculator uses the 3-phase power formula:
Where:
Energy consumption is then calculated as: \[ kWh = \frac{P}{1000} \times hours \]
Explanation: The formula accounts for the three-phase system characteristics and converts the result to kilowatt-hours for energy consumption measurement.
Details: Accurate power consumption calculation is crucial for energy cost estimation, system efficiency analysis, electrical load management, and preventive maintenance planning in industrial applications.
Tips: Enter line-to-line voltage in volts, current in amperes, power factor as a decimal (0-1), and operating hours. All values must be 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 crucial because low power factor increases current draw and reduces system efficiency.
Q2: How accurate is this calculation for real-world applications?
A: The calculation provides theoretical values. Actual consumption may vary due to motor efficiency, load variations, and voltage fluctuations.
Q3: Can this calculator be used for single-phase systems?
A: No, this calculator is specifically designed for 3-phase systems. Single-phase calculations use different formulas.
Q4: What is typical power factor for industrial motors?
A: Typical power factor ranges from 0.8 to 0.95 for most industrial motors under full load, but decreases significantly under light loads.
Q5: How can I improve power factor?
A: Power factor can be improved through capacitor banks, synchronous condensers, or using high-efficiency motors designed for better power factor.
