1. What is kVA to kW Conversion?

Definition: This calculator converts apparent power (kVA) to real power (kW) using the power factor.

Purpose: It helps electrical engineers and technicians determine the actual usable power in a 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 available to do work.

3. Importance of kVA to kW Conversion

Details: Understanding the difference between apparent and real power is crucial for proper electrical system design, equipment sizing, and energy efficiency.

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 is power factor?
A: Power factor is the ratio of real power to apparent power, representing the efficiency of power usage in a system.

Q2: What's a typical power factor value?
A: For most industrial loads, power factor ranges from 0.8 to 0.95. Residential typically has 0.9-1.0.

Q3: Why is kW less than kVA?
A: kW represents actual usable power, while kVA includes both usable power and reactive power that doesn't do actual work.

Q4: How can I improve power factor?
A: Using power factor correction capacitors, synchronous condensers, or avoiding lightly loaded motors can improve power factor.

Q5: When would kW equal kVA?
A: When power factor is 1.0 (perfect efficiency), which occurs with purely resistive loads like incandescent lighting or heaters.
