7 Choice of architecture details
This is the second stage in designing of the electrical installation. During this stage
we carry out the following choices are carried out:
b Layout,
b Centralized or decentralized distribution,
b Presence of back-up generators,
b Presence of uninterruptible power supplies,
b Configuration of LV circuits,
b Architecture combinations.
7.1 Layout
Position of the main MV and LV equipment on the site or in the building.
This layout choice is applied to the results of stage 1.
Selection guide:
b Place power sources as close as possible to the barycenter of power consumers,
b Reduce atmospheric constraints: building dedicated premises if the layout in the
workshop is too restrictive (temperature, vibrations, dust, etc.),
b Placing heavy equipment (transformers, generators, etc) close to walls or main
exists for ease of maintenance,
A layout example is given in the following diagram (Fig. D12):
