Microsystem criteria in electrical installations ecodesign

The ecodesign is developing a strong encouragement towards the energy saving balanced with other performances and requires new approaches that this paper begins to highlight. The distribution system management has to facilitate innovations, changes and the complying with these improvements. Together to energy saving, reduced voltage-drops and losses, the system modeling with components of smaller size allows to guarantee a higher value of current densities, reduced volume of conductors and other related goals of efficiencies. Microsystem criteria are highlighted introducing few specific parameters to assist the system design that rises generally as a comprehensive solution of a non linear system of many elements, grouping adequately the supplying loads, adopting circuit with conductors/cables in bunch, in loop or in rope design. © IEEE 2010.
