1. What Is The 3 Phase Motor Power Consumption Formula?

The 3 phase motor power consumption formula calculates the energy usage in kilowatt-hours (kWh) for three-phase electrical motors commonly used in industrial applications in India. It provides an accurate measurement of electrical energy consumption.

2. How Does The Calculator Work?

The calculator uses the 3 phase motor power consumption formula:

\[ E = \sqrt{3} \times V \times I \times PF \times t / 1000 \]

Where:

\( E \) — Energy consumption (kWh)
\( V \) — Voltage (Volts)
\( I \) — Current (Amperes)
\( PF \) — Power Factor (dimensionless)
\( t \) — Time (hours)

Explanation: The formula accounts for the three-phase power system characteristics, converting the apparent power to actual energy consumption in kilowatt-hours.

3. Importance Of Energy Consumption Calculation

Details: Accurate energy consumption calculation is crucial for industrial energy management, cost estimation, efficiency analysis, and electrical system design in Indian industrial applications.

4. Using The Calculator

Tips: Enter voltage in volts, current in amperes, power factor (typically between 0.7-1.0), and time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the √3 factor used in the formula?
A: The √3 factor accounts for the phase relationship in three-phase AC power systems, converting line-to-line voltage to phase voltage.

Q2: What is a typical power factor value for industrial motors?
A: Typical power factor values range from 0.7 to 0.95, depending on motor type, load conditions, and efficiency.

Q3: How does this calculation help in energy cost estimation?
A: By calculating kWh consumption, you can multiply by your electricity tariff rate to estimate operational costs for motor running.

Q4: Are there limitations to this calculation?
A: This calculation assumes balanced three-phase supply and constant operating conditions. Variations in voltage, current, or power factor during operation may affect accuracy.

Q5: Can this formula be used for single-phase motors?
A: No, this formula is specifically for three-phase systems. Single-phase motors use a different calculation without the √3 factor.
