The architecture design
The architecture design considered in this document starts at the preliminary design stage (see Fig. D3 step1). It generally covers the levels of MV/LV main distribution, LV power distribution, and exceptionally the terminal distribution level. (see Fig. D2).
In buildings all consumers are connected in low voltage. It means that MV distribution consists in:
- connection to utility,
- distribution to MV/LV substation(s),
- MV/LV substation(s) itself.
The design of an electrical distribution architecture can be described by a 3-stage process, with iterative possibilities. This process is based on taking into account of the installation characteristics and criteria to be satisfied.
