4 General
4.1 Concept of electrical installation
Any low-voltage electrical installation is to be considered as a set of electrical equipment having
the tollowing functions (see Figure 1):
• supply (e.g. local generator, photovoltaic systems, wind turbine, batteries);
• distribution (e.g. distribution board, wiring systems, socket-outlets);
• consumption (e.g. fans, lighting, appliances, pumps, batteries).
4.2 Architecture and operating modes of Installation
Various architectures and operating modes of installations are defined in Annex A.
Selection of the appropriate installation architectures shall be undertaken according to the environment of the installation and its foreseeable future modification.
5 Local power sources (supplies)
Examples of local power sources are:
• local rotating generating set:
• storage units:
• photovoltaic system;
• wind turbine.
Any combination of different types of local power sources is possible. Where power sources use renewable energy, which provides intermittent supply, storage of this energy is recommended.
