1. What is kVA to kW Conversion for 3 Phase?

Definition: This calculator converts apparent power (kVA) to real power (kW) in three-phase electrical systems using the power factor.

Purpose: Helps electrical engineers and technicians determine the actual usable power in a three-phase system.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Real power (kilowatts)
• \( kVA \) — Apparent power (kilovolt-amperes)
• \( PF \) — Power factor (unitless, between 0 and 1)

Explanation: The apparent power is multiplied by the power factor to determine the actual power being used to do work.

3. Importance of kVA to kW Conversion

Details: Proper conversion ensures accurate power system sizing, efficient energy use, and correct equipment selection.

4. Using the Calculator

Tips: Enter the apparent power in kVA and power factor (default 0.8). Power factor must be between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kVA and kW?
A: kVA is apparent power (total power in system), while kW is real power (actual usable power).

Q2: What's a typical power factor value?
A: Industrial systems often use 0.8-0.95, while residential might be 0.7-0.9.

Q3: Why is power factor important?
A: Low power factor means you're paying for power you can't use, and may need larger equipment.

Q4: Does this work for single-phase systems?
A: Yes, the same formula applies, though three-phase calculations often include additional factors.

Q5: How can I improve power factor?
A: Using power factor correction capacitors or synchronous motors can help improve PF.
