1. What is kW to kVA Conversion?

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

Purpose: It helps electrical engineers and technicians understand the relationship between real and apparent power in AC circuits.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The real power is divided by the power factor to calculate the apparent power needed in the system.

3. Importance of kW to kVA Conversion

Details: Understanding this relationship is crucial for proper sizing of electrical equipment like generators, transformers, and UPS systems.

4. Using the Calculator

Tips: Enter the real power in kW and power factor (default 0.8). Power factor must be between 0.01 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kW and kVA?
A: kW measures real power (actual work done), while kVA measures apparent power (total power in the circuit).

Q2: What is a typical power factor value?
A: Most industrial equipment has a PF between 0.8 and 0.95. Residential might be 0.9-1.0.

Q3: Why does power factor affect kVA?
A: Lower power factor means more current is needed to deliver the same real power, increasing the apparent power.

Q4: When would I need this conversion?
A: When sizing electrical equipment, calculating system capacity, or analyzing power efficiency.

Q5: Can kVA be less than kW?
A: No, since power factor is ≤1, kVA is always ≥ kW.
