How current actually splits across the three phases at each measurement point, so you know whether unbalance is general, localised, or tied to the hour of day.
The Load Balancing module analyses how load distributes across phases over the chosen period. An uneven split heats conductors, reduces the transformer's usable capacity, and shows up as voltage unbalance downstream — which is what the Grid Code assesses.
The analysis runs per measurement point over a full period rather than an instantaneous reading, because the unbalance that matters is the one that persists.
Choose the period and the substation, and the analysis runs over that window's readings. Then you simulate: state how many amperes would move from one phase to another — up to four transfers at once — and the module computes the unbalance you would be left with, before touching a single cable.
