1. What is a Three Phase to Single Phase Calculator?

Definition: This calculator converts three-phase power (kW) to equivalent single-phase power (kW) at the same voltage.

Purpose: It helps electrical engineers and technicians determine the equivalent single-phase power when working with three-phase systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{1ph} \) — Single-phase power (kW)
• \( P_{3ph} \) — Three-phase power (kW)

Explanation: The three-phase power is divided by √3 (approximately 1.732) to get the equivalent single-phase power at the same voltage.

3. Importance of Power Conversion

Details: This conversion is essential when designing electrical systems, sizing equipment, or comparing single-phase and three-phase power requirements.

4. Using the Calculator

Tips: Enter the three-phase power in kilowatts (kW). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why do we divide by √3?
A: In balanced three-phase systems, the power is distributed across three phases, so the equivalent single-phase power is the total power divided by √3.

Q2: Does this conversion work for both current and power?
A: This specific calculator is for power conversion. Current conversion would require additional voltage information.

Q3: Is this conversion valid for unbalanced systems?
A: No, this calculation assumes a perfectly balanced three-phase system.

Q4: What's the typical application for this conversion?
A: Useful when you need to compare or convert between three-phase and single-phase equipment ratings.

Q5: Does this account for power factor?
A: This calculates real power conversion. For apparent power, power factor would need to be considered separately.
