Unbalanced Current Calculation
Unbalanced current information is available on 3-phase models only.
This section explains how the PX3 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:

L2 = 5.2 amps
L3 = 4.0 amps
