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 determine the apparent power needed for proper sizing of electrical equipment.

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 required by the system.

3. Importance of kW to kVA Conversion

Details: Proper conversion ensures correct sizing of generators, transformers, and other electrical equipment to handle both real and reactive power.

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 (1 = perfect efficiency).

Q2: What's a typical power factor value?
A: Industrial loads typically have 0.8-0.95, while residential may be 0.9-1.0.

Q3: 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.

Q4: Can power factor be greater than 1?
A: No, power factor ranges from 0 to 1 (0-100%).

Q5: How do I improve power factor?
A: Use power factor correction capacitors or synchronous condensers to reduce reactive power.
