1. What is the 3-Phase Power Formula?

The 3-phase power formula calculates electrical energy consumption in kilowatt-hours (kWh) for three-phase electrical systems. It provides an accurate measurement of power usage in industrial and commercial applications where three-phase power is commonly used.

2. How Does the Calculator Work?

The calculator uses the 3-phase power formula:

\[ kWh = \sqrt{3} \times A \times V \times H / 1000 \]

Where:

\( A \) — Current in amperes (amps)
\( V \) — Voltage in volts
\( H \) — Time in hours
\( \sqrt{3} \) — Constant for 3-phase systems (approximately 1.732)
1000 — Conversion factor from watts to kilowatts

Explanation: The formula calculates the total energy consumption by accounting for the three-phase power factor and converting the result to kilowatt-hours.

3. Importance of kWh Calculation

Details: Accurate kWh calculation is essential for energy monitoring, cost estimation, electrical system design, and efficiency analysis in three-phase power systems.

4. Using the Calculator

Tips: Enter current in amps, voltage in volts, and time in hours. All values must be positive numbers. The calculator will compute the energy consumption in kilowatt-hours.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between single-phase and three-phase power?
A: Single-phase power uses two wires (one phase and one neutral) while three-phase power uses three or four wires (three phases and optionally a neutral), providing more efficient power delivery for heavy loads.

Q2: When should I use the 3-phase power formula?
A: Use this formula for calculating energy consumption in three-phase electrical systems, typically found in industrial settings, large commercial buildings, and high-power equipment.

Q3: What is the significance of the √3 factor?
A: The √3 factor (approximately 1.732) accounts for the phase difference in three-phase systems and converts line-to-line voltage to phase voltage in the power calculation.

Q4: Can this formula be used for both balanced and unbalanced loads?
A: This formula assumes a balanced load across all three phases. For unbalanced loads, more complex calculations are required for accurate results.

Q5: How does power factor affect the calculation?
A: This formula assumes a power factor of 1 (perfect efficiency). For systems with different power factors, additional adjustments would be needed for precise calculations.
