Recommendations for small renewable energy and hybrid systems for rural electrification - Part 5: Protection against electrical hazards
Decentralised Rural Electrification Systems (DRES) are designed to supply electric power for sites which are not connected to a large interconnected system, or a national grid, in order to
meet basic needs.
The majority of these sites are:
a) isolated dwellings;
b) village houses;
c) community services (public lighting, pumping, health centers, places of worship or cultural
activities, administrative buildings, etc.); and
d) economic activities (workshops, micro-industry, etc).
The DRE systems fall into three categories:
a) process electrification systems (for example for pumping);
b) individual electrification systems (IES) for single users; and
c) collective electrification systems (CES) for multiple users.
Process or individual electrification systems exclusively consist of two subsystems:
a) an electric energy generation subsystem; and
b) the user’s electrical installation.
Collective electrification systems, however, consist of 3 subsystems:
a) an electric ener
