The LV network starts from the low voltage terminals of the distribution transformer. The following information is essential for modelling of the low-voltage network;
1 section length;
2 conductor size of each section;
3 connected load for each group of consumers;
4 number of consumers in each group; and
5 total connected load on the transformer.
Sample LV network emanating from distribution transformer located in high, medium and low load density pockets of the circle and covering various categories of consumers should be modelled to form the primary for determining the improvement in whole LV network.
