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 conversion is crucial for proper sizing of electrical equipment like transformers and generators.

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 is power factor?
A: Power factor is the ratio of real power to apparent power, representing the efficiency of power usage (typically 0.8-0.95 for industrial equipment).

Q2: Why is apparent power important?
A: Electrical equipment must be sized for apparent power (kVA) as it represents the total power flowing in the system.

Q3: What's a typical power factor value?
A: Common values are 0.8 for motors, 0.9-0.95 for modern equipment, and 1.0 for purely resistive loads.

Q4: Can power factor be greater than 1?
A: No, power factor ranges from 0 to 1 in normal operating conditions.

Q5: How do I improve power factor?
A: Use power factor correction capacitors or synchronous condensers to bring power factor closer to 1.
