1. What is 3 Phase Amps to kVA Conversion?

The 3 phase amps to kVA conversion calculates the apparent power in kilovolt-amps (kVA) from the current in amps (A) and voltage in volts (V) for three-phase electrical systems. This is essential for sizing electrical equipment and determining power requirements.

2. How Does the Calculator Work?

The calculator uses the 3 phase formula:

Where:

• \( Amps \) — Current in amperes (A)
• \( Volts \) — Voltage in volts (V)
• \( \sqrt{3} \) — Constant for three-phase systems (≈1.732)
• \( 1000 \) — Conversion factor from VA to kVA

Explanation: The formula accounts for the phase difference in three-phase systems through the √3 factor, converting the product of amps and volts to kilovolt-amps.

3. Importance of kVA Calculation

Details: kVA represents apparent power in an electrical circuit, crucial for sizing transformers, generators, and circuit breakers in three-phase systems.

4. Using the Calculator

Tips: Enter current in amps and voltage in volts. Both values must be positive numbers. The calculator will compute the apparent power in kVA.

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 (volts × amps × power factor). kVA includes both real and reactive power.

Q2: Why use √3 in three-phase calculations?
A: The √3 accounts for the 120° phase difference between the three phases in a balanced three-phase system.

Q3: Can I use this for single-phase systems?
A: No, for single-phase systems use kVA = (Amps × Volts)/1000 (without the √3 factor).

Q4: What's typical voltage for three-phase systems?
A: Common voltages include 208V, 240V, 380V, 400V, 415V, 480V, 600V, and higher for industrial applications.

Q5: How accurate is this calculation?
A: This provides theoretical apparent power. Actual system performance may vary due to power factor, efficiency, and other factors.
