Load Meter Calculation

Load meter calculation is a crucial process in electrical engineering, enabling accurate measurement and billing of energy consumption. This calculator simplifies the process, ensuring precise results.

1. Select the voltage.
2. Enter the current.
3. Choose the power factor.
4. Click ‘Calculate’.

The load meter calculation is based on the formula: Apparent Power (kVA) = Voltage (V) × Current (A) × Power Factor. The calculator converts the result to kW using the power factor.

• Always use accurate voltage and current readings.
• Consider using a higher power factor for more precise results.
• Regularly calibrate your load meter for accurate readings.

What is the difference between apparent power and real power?

Apparent power is the total power supplied to a circuit, while real power is the actual power consumed by the load.
