Hz To Kw Formula:
| From: | To: |
The Hz To Kw calculation converts electrical parameters (voltage, current, power factor, and frequency) into power in kilowatts. This is particularly useful in three-phase AC power systems for determining the actual power consumption or generation.
The calculator uses the formula:
Where:
Explanation: This formula calculates the real power in kilowatts for a three-phase AC electrical system, accounting for the power factor which represents the phase difference between voltage and current.
Details: Accurate power calculation is essential for electrical system design, energy consumption analysis, equipment sizing, and cost estimation in industrial and commercial applications.
Tips: Enter voltage in volts, current in amperes, power factor (between 0 and 1), and frequency in hertz. All values must be positive numbers.
Q1: Why is the √3 factor included in the formula?
A: The √3 factor accounts for the phase relationship in three-phase AC systems, where the voltage between any two phases is √3 times the phase voltage.
Q2: What is power factor and why is it important?
A: Power factor represents the ratio of real power to apparent power. It indicates how effectively electrical power is being used, with 1.0 being ideal.
Q3: Can this calculator be used for single-phase systems?
A: No, this formula is specifically for three-phase systems. For single-phase systems, use: kW = V × I × PF / 1000.
Q4: Why divide by 1000 in the formula?
A: The division by 1000 converts the result from watts to kilowatts (1 kW = 1000 W).
Q5: What are typical power factor values?
A: Power factor typically ranges from 0.7 to 1.0. Industrial motors often have power factors around 0.8-0.9, while purely resistive loads have a power factor of 1.0.
