Step 1: Choice of distribution architecture fundamentals
This involves defining the general features of the electrical installation. It is based
on taking account of macroscopic characteristics concerning the installation and its
usage.
These characteristics have an impact on the connection to the upstream network,
MV circuits, the number of transformer substations, etc.
At the end of this step, we have several distribution schematic diagram solutions,
which are used as a starting point for the single-line diagram. The definitive choice is
confirmed at the end of the step 2.
