1. What is a kVA to kWh Converter?

Definition: This calculator converts apparent power (kVA) to energy consumption (kWh) using power factor and time duration.

Purpose: It helps electrical engineers, facility managers, and energy auditors determine actual energy usage from apparent power measurements.

2. How Does the Converter Work?

The converter uses the formula:

\[ E_{kWh} = kVA \times PF \times t \]

Where:

\( E_{kWh} \) — Energy in kilowatt-hours
\( kVA \) — Apparent power in kilovolt-amperes
\( PF \) — Power factor (0 to 1)
\( t \) — Time duration in hours

Explanation: The apparent power is multiplied by the power factor to get real power (kW), then multiplied by time to get energy consumption.

3. Importance of kVA to kWh Conversion

Details: Accurate conversion helps in energy billing, generator sizing, electrical system design, and energy efficiency analysis.

4. Using the Converter

Tips: Enter the apparent power in kVA, power factor (default 0.8), and time duration in hours. Power factor must be between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kVA and kWh?
A: kVA measures apparent power (voltage × current), while kWh measures energy consumption (power × time).

Q2: What's a typical power factor value?
A: Most electrical systems operate at 0.8-0.95 power factor. Industrial motors might be 0.85, while purely resistive loads are 1.0.

Q3: Why is power factor important?
A: It represents the efficiency of power usage. Lower power factors mean more current is needed for the same real power.

Q4: Can I use this for three-phase systems?
A: Yes, if the kVA value already accounts for three-phase (line-to-line voltage × current × √3).

Q5: How do I find the power factor?
A: Use a power meter or check equipment specifications. Utilities often measure power factor at the service entrance.
