## Phase to Ground Voltage Formula

The following formula is used to calculate the Phase to Ground Voltage.

Vp-g = Vp-p / 1.73

Variables:

- Where Vp-g is the Phase to Ground Voltage (volts)
- Vp-p is the phase to phase voltage (volts)

To calculate the phase-to-ground voltage, divide the phase-to-phase voltage by a value of 1.73.

## How to Calculate Phase to Ground Voltage?

The following two example problems outline how to calculate the Phase to Ground Voltage.

**Example Problem #1:**

- First, determine the phase to phase voltage (volts). In this example, the phase to phase voltage (volts) is measured to be 45.
- Finally, calculate the Phase to Ground Voltage using the formula above:

Vp-g = Vp-p / 1.73

Inserting the values from above and solving the equation with the imputed values gives:

Vp-g = 45 / 1.73 = 26.011 (volts)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

phase to phase voltage (volts) = 81

Entering these values into the formula or calculator above gives us::

Vp-g = 81 / 1.73 = 46.820 (volts)
