1. What is the 3 Phase Power Formula?

The 3 phase power formula calculates electrical current (amps) from power (kilowatts), voltage, and power factor in a three-phase AC system. It provides accurate current estimation for balanced three-phase loads.

2. How Does the Calculator Work?

The calculator uses the 3 phase power formula:

\[ I = \frac{15 \times 1000}{V \times \sqrt{3} \times PF} \]

Where:

Explanation: The formula converts 15 kW to watts, then divides by the product of voltage, square root of 3, and power factor to calculate the current.

3. Importance of Current Calculation

Details: Accurate current calculation is crucial for proper electrical system design, circuit breaker sizing, wire selection, and ensuring equipment operates within safe current limits.

4. Using the Calculator

Tips: Enter line-to-line voltage in volts and power factor (typically between 0.8-1.0). All values must be valid (voltage > 0, power factor between 0.01-1.0).

5. Frequently Asked Questions (FAQ)

Q1: Why is the power factor important in this calculation?
A: Power factor represents the ratio of real power to apparent power. Lower power factors result in higher current for the same real power, affecting conductor sizing and system efficiency.

Q2: What is typical voltage range for 3 phase systems?
A: Common voltages include 208V, 240V, 380V, 400V, 415V, 480V, and 600V, depending on the country and application.

Q3: How does this differ from single phase calculation?
A: Single phase uses I = P/(V×PF) while three phase uses I = P/(V×√3×PF). Three phase systems are more efficient for power distribution.

Q4: What if I have a different power value than 15 kW?
A: This calculator is specifically designed for 15 kW. For other power values, the formula would need to be adjusted accordingly.

Q5: When should this calculation be used?
A: This calculation is essential for electrical engineers, technicians, and anyone designing or maintaining three-phase electrical systems with 15 kW loads.
