Learn how to use the Amperes Per Phase Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the voltage in volts (V) of your electrical system.
  2. Enter the power in kilowatts (kW) that you want to calculate the current for.
  3. Enter the power factor (PF) of your electrical system. The power factor should be between 0 and 1.
  4. Click the "Calculate" button to compute the current per phase.
  5. The result will be displayed in amperes (A).

Working Principle

The calculator uses the formula for calculating the current per phase in a three-phase electrical system:

Iphase = P / (√3 × V × PF)

Where:

  • Iphase is the current per phase in amperes (A)
  • P is the power in watts (W)
  • V is the voltage in volts (V)
  • PF is the power factor

Example

Suppose you have a three-phase electrical system with a voltage of 440V, a power of 15kW, and a power factor of 0.85. To calculate the current per phase:

  1. Enter 440 in the voltage field.
  2. Enter 15 in the power field.
  3. Enter 0.85 in the power factor field.
  4. Click the "Calculate" button.

The result will be 24.16A (amperes).
