1. What is 3 Phase Power Consumption?

This calculator estimates the energy consumption of a 3000W (3kW) load in a three-phase power system over a specified period of time. It converts watts to kilowatt-hours (kWh), which is the standard unit for energy billing.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• 3000 — Power rating in watts (3kW)
• h — Operating hours
• 1000 — Conversion factor from watts to kilowatts

Explanation: The formula calculates total energy consumption by multiplying power (in kW) by time (in hours).

3. Importance of Power Calculation

Details: Accurate power consumption calculation helps in energy management, cost estimation, and electrical system design for three-phase equipment.

4. Using the Calculator

Tips: Enter the operating hours of your 3000W three-phase equipment. The result shows energy consumption in kilowatt-hours (kWh).

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation different for single-phase systems?
A: The basic energy calculation is the same, but three-phase systems typically have different wiring and power factor considerations.

Q2: Does this account for power factor?
A: This simple calculation assumes unity power factor (1.0). For precise calculations, power factor should be considered.

Q3: What's the difference between kW and kWh?
A: kW is power (energy per unit time), while kWh is energy (power × time).

Q4: How can I estimate my electricity cost from this?
A: Multiply the kWh result by your electricity rate (per kWh) to estimate cost.

Q5: Is 3000W typical for three-phase equipment?
A: 3000W (3kW) is common for medium-sized three-phase motors, pumps, and industrial equipment.
