Line Current Formula
The following formula is used to calculate the Line Current.
IL = IP * SQRT(3)
- Where IL is the Line Current (amps)
- IP is the total phase current (amps)
How to Calculate Line Current?
The following two example problems outline how to calculate the Line Current.
Example Problem #1:
- First, determine the total phase current (amps). In this example, the total phase current (amps) is measured to be 56.
- Finally, calculate the Line Current using the formula above:
IL = IP * SQRT(3)
Inserting the values from above and solving the equation with the imputed values gives:
IL = 56 * SQRT(3) = 96.99 (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 phase current (amps) = 82
Entering these values into the formula above gives :
IL = 82 * SQRT(3) = 142.028 (amps)
