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 account of the installation characteristics and criteria to be satisfied.
