How To Calculate 3 Phase Energy Meter Reading

3 Phase Energy Meter Reading Calculator





Understanding how to calculate 3 phase energy meter readings is crucial for businesses and households to monitor and manage their electricity consumption effectively.

  1. Enter the readings for each phase (Phase 1, Phase 2, and Phase 3) in the respective input fields.
  2. Select the frequency (50 Hz or 60 Hz) from the dropdown menu.
  3. Click the “Calculate” button to see your results and a visual representation of your energy consumption.

The formula to calculate the total energy consumption in kWh for a 3 phase system is:

Total Energy = (Phase 1 Reading + Phase 2 Reading + Phase 3 Reading) * (2 * π * Frequency) / (3 * Square Root of 3)

Comparison of Energy Consumption at Different Frequencies
Frequency (Hz) Total Energy (kWh)
50 12.57
60 15.71
  • Regularly monitor your energy consumption to identify any anomalies or areas for improvement.
  • Consider using energy-efficient appliances and equipment to reduce your consumption.
  • Consult with a professional if you notice any significant fluctuations in your energy consumption.
