Three Phase Voltage To Single Phase Voltage Calculation

Introduction & Importance

Three phase to single phase voltage calculation is crucial in electrical engineering and power systems. It helps determine the equivalent single phase voltage from a three phase supply, which is essential for various applications, including motor control, lighting, and power distribution.

How to Use This Calculator

1. Select the number of phases (1, 2, or 3).
2. Enter the voltage value in volts (V).
3. Click the ‘Calculate’ button.

Formula & Methodology

The formula to convert three phase voltage to single phase voltage is:

V_s = V_p / √3

Where:

• V_s is the single phase voltage.
• V_p is the phase voltage (line voltage for 3-phase).
