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:
- First, determine the line voltage (volts). In this example, the line voltage (volts) is measured to be 47.
- 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)
