[en] One original application of the distribution network development, based on existing HV network, is presented for the rural electrification of developing countries.
Supply of a few kVA to remote site needs specific installations. We have developed, installed and experimented one practical application from April 17th, 2002 in Makola (Congo-Brazzaville, 30 km far from Pointe Noire).
We have investigated the case where a HV OHL exists in the vicinity of the village. Our application is a one-phase connection to a 220 kV line with a local demand estimated at 50 kVA (about 500 people) in a first step. We have adapted the existing technology of SF6 inductive voltage transformer in order to supply 50 kVA instead of a few VA.
The paper will present the problems met during the design of this specific installation compared to classical substation, and the results of first months of use.
