Enter the line voltage (volts) into the calculator to determine the Line to Phase Voltage.

## Line to Phase Voltage Formula

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

Vphase = VL-L / 1.732

Variables:

• Where Vphase is the Line to Phase Voltage (volts)
• VL-L is the line voltage (volts)

To calculate the phase voltage from line to line voltage, divide the line-to-line voltage by 1.732.

## How to Calculate Line to Phase Voltage?

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

Example Problem #1:

1. First, determine the line voltage (volts). In this example, the line voltage (volts) is measured to be 47.
2. Finally, calculate the Line to Phase Voltage using the formula above:

Vphase = VL-L / 1.732

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

Vphase = 47 / 1.732 = 27.136 (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:

line voltage (volts) = 69

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

Vphase = 69 / 1.732 = 39.83 (volts)
