Unbalanced Current Calculation
Unbalanced current information is available on 3-phase models only.
This section explains how the PXE calculates the unbalanced current
percentage.
Calculation:
1. Calculate the average current of all 3 lines.
Average current = (L1+L2+L3) / 3
2. Calculate each line's current unbalance by having each line current
subtracted and divided with the average current.
L1 current unbalance = (L1 - average current) / average
current
L2 current unbalance = (L2 - average current) / average
current
L3 current unbalance = (L3 - average current) / average
current
3. Determine the maximum absolute value among three lines' current
unbalance values.
Maximum (|L1 current unbalance|, |L2 current unbalance|,
|L3 current unbalance|)
4. Convert the maximum value to a percentage.

Example:
Each line's current:
L1 = 5.5 amps
L2 = 5.2 amps
L3 = 4.0 amps
