1. What is a kVA to kW Converter?

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 power consumption in kilowatts from the apparent power in kilovolt-amperes.

2. How Does the Converter Work?

The converter uses the formula:

Where:

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

Explanation: The apparent power (kVA) is multiplied by the power factor to get the actual usable power (kW) that performs work.

3. Importance of kVA to kW Conversion

Details: Understanding the difference between kVA and kW is crucial for proper electrical system design, generator sizing, and energy efficiency calculations.

4. Using the Converter

Tips: Enter the apparent power in kVA and the 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 (volts × amps), while kW is real power that does actual work. The ratio between them is the power factor.

Q2: What's a typical power factor value?
A: For most industrial loads, power factor ranges from 0.8 to 0.95. Residential power factors are typically higher (0.95-1.0).

Q3: Why is power factor important?
A: Low power factor means you're paying for power (kVA) that isn't doing useful work (kW), and may incur utility penalties.

Q4: Can power factor be greater than 1?
A: No, power factor ranges from 0 to 1. Values above 1 would violate the laws of physics.

Q5: How can I improve power factor?
A: Use power factor correction capacitors, minimize idling motors, and replace oversized motors with properly sized ones.
