MV public distribution networks throughout the world

In a country, the Transmission and Public Distribution networks ensure the transfer of electrical energy from points of production to consumer units. The points of production are power stations that generate electrical energy from various primary energy sources (nuclear, hydro-electric, coal....) The points of consumption in MV - Medium Voltage - are substations, from which the energy is delivered to customers (subscribers). This takes place via the "MV distribution system" which is the object of this "Cahier Technique" report. In this "Cahier Technique" report, after having described the various types of distribution networks and the distributor's role, the reader who is not familiar with MV will find details on: - topologies of MV networks, - substations, - protection and telecontrol devices. Comment: In this "Cahier Technique" report, the term MV applies to any voltage from a few kV to 40 kV.
