Phase Current From Line Current Formula
The following formula is used to calculate the Phase Current.
Ip = IL / SQRT(3)
- Where Ip is the Phase Current (amps)
- IL is the total line current (amps)
How to Calculate Phase Current From Line Current?
The following two example problems outline how to calculate the Phase Current from line current.
Example Problem #1:
- First, determine the total line current (amps). In this example, the total line current (amps) is measured to be 61.
- Finally, calculate the Phase Current using the formula above:
Ip = IL / SQRT(3)
Inserting the values from above and solving the equation with the imputed values gives:
Ip = 61 / SQRT(3) = 35.21 (amps)
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:
total line current (amps) = 18
Entering these values into the formula above gives us::
Ip = IL / SQRT(3) = 10.39 (amps)
