Elimination des défauts des départs 10 et 30 KV par effet capacitif

Abstract

The electrical distribution networks is an essential part for supplying power to different consumers LV and MV, are considered highly critical infrastructure for the industrial and economic development of countries, but there are several anomalies (overvoltage, unbalance, short-circuit ... etc.), this requires a good electrical system installed to protect this network. The proper study of welfare système in electrical distribution medium voltage (10 kV and 30 kV) against schorts-circuits between phases or phase to earth to provide both good security of persons against electric shock and property against destructive effects of strong currents on the cable, lines and power transformers ... etc. And a good overall service continuity of the distribution system by isolating part of the default network in order to preserve function. The contribution of this thesis consists of teaching the case study electrical distribution LV of the city of Ain-Témouchent .
