Phase to Ground Voltage Calculator Calculator Usage Guide

Learn how to use the Phase to Ground Voltage Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the line-to-line voltage (VLL) of your three-phase electrical system.
  2. Enter the phase angle (θ) in degrees. The default value is 30 degrees, which is typical for many three-phase systems.
  3. Click the "Calculate" button to compute the phase to ground voltage (VPG).
  4. The result will be displayed in volts (V).

Working Principle

The phase to ground voltage in a three-phase system can be calculated using the formula VPG = VLL * sin(θ), where VLL is the line-to-line voltage and θ is the phase angle.

Example

If the line-to-line voltage of a three-phase system is 400V and the phase angle is 30 degrees, the phase to ground voltage would be:

VPG = 400V * sin(30°) = 400V * 0.5 = 200V

Applications

This calculator is useful for electrical engineers, technicians, and anyone working with three-phase electrical systems. It helps in determining the safety and performance of electrical installations.
