What is Phase to Ground Voltage?

Phase to Ground Voltage is the voltage measured between one phase conductor and the ground or neutral. It is an important parameter in electrical systems, particularly in three-phase systems, to ensure proper insulation and safety.

Example Calculation 1

Let's assume the following value:

Using the formula:

\[ V_{p-g} = \frac{400}{1.73} \approx 231.21 \, \text{volts} \]

The Phase to Ground Voltage is approximately 231.21 volts.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[ V_{p-g} = \frac{230}{1.73} \approx 132.95 \, \text{volts} \]

The Phase to Ground Voltage is approximately 132.95 volts.
