Resolution
The current unbalance is calculated using the following equation:

I unbalance = (Max phase current - Min phase current) / Avg 3 phase current * 100

For example:

Ia = 100 A
Ib = 120 A
Ic = 150 A

Therefore, Max phase current = 150 A, Min phase current = 100 A, and Avg 3 phase current = (100 + 120 + 105) / 3 = 108.3 A.

I unbalance = (150 - 100) / 108.3 * 100 = 46.2 % unbalance
