1. What is Three Phase Power Calculation?

Three phase power calculation is used to determine the real power (wattage) in a three-phase electrical system. It accounts for voltage, current, power factor, and the √3 factor that represents the phase relationship in three-phase systems.

2. How Does the Calculator Work?

The calculator uses the three phase power formula:

\[ W = V \times I \times \sqrt{3} \times PF \]

Where:

\( W \) — Power in watts
\( V \) — Voltage in volts
\( I \) — Current in amps
\( \sqrt{3} \) — Approximately 1.732 (dimensionless)
\( PF \) — Power factor (dimensionless, between 0 and 1)

Explanation: The formula calculates real power in a balanced three-phase system by multiplying line-to-line voltage, line current, the √3 factor, and power factor.

3. Importance of Three Phase Power Calculation

Details: Accurate power calculation is essential for electrical system design, load balancing, energy consumption analysis, and proper equipment sizing in industrial and commercial applications.

4. Using the Calculator

Tips: Enter voltage in volts, current in amps, and power factor (between 0 and 1). All values must be valid (voltage > 0, current > 0, 0 ≤ PF ≤ 1).

5. Frequently Asked Questions (FAQ)

Q1: What is the √3 factor in three-phase calculations?
A: The √3 factor (approximately 1.732) accounts for the phase difference between the three phases in a balanced three-phase system.

Q2: What is power factor and why is it important?
A: Power factor is the ratio of real power to apparent power. It indicates how effectively electrical power is being used and affects system efficiency.

Q3: When is this calculation most applicable?
A: This calculation is used for balanced three-phase systems commonly found in industrial motors, generators, and power distribution systems.

Q4: What's the difference between line and phase values?
A: In three-phase systems, line values refer to measurements between lines, while phase values refer to measurements between line and neutral.

Q5: How does this differ from single-phase power calculation?
A: Single-phase power calculation uses W = V × I × PF without the √3 factor, as there's no phase relationship to account for.
