Sequence Current Formula
The following formula is used to calculate the Sequence Current.
Iseq = Vseq / Zseq
- Where Iseq is the Sequence Current (amps)
- Vseq is the positive sequence voltage (volts)
- Zseq is the positive sequence impedance (ohms)
How to Calculate Sequence Current?
The following two example problems outline how to calculate the Sequence Current.
Example Problem #1:
- First, determine the positive sequence voltage (volts). In this example, the positive sequence voltage (volts) is measured to be 73.
- Next, determine the positive sequence impedance (ohms). For this problem, the positive sequence impedance (ohms) is calculated to be 4.
- Finally, calculate the Sequence Current using the formula above:
Iseq = Vseq / Zseq
Inserting the values from above and solving the equation with the imputed values gives:
Iseq = 73 / 4 = 18.25 (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:
positive sequence voltage (volts) = 52
positive sequence impedance (ohms) = 20
Entering these values into the formula or calculator above gives us::
Iseq = 52 / 20 = 2.6 (amps)
