Permanent electrical power
Tokamak Tore Supra

The permanent power required for the auxiliaries comes from a 15 kV network distributed in the Cadarache center from the 63 kV EDF network. The dispersal of equipment over several hectares has led to the construction of 5 distribution substations with a total power of 10 MVA. The main auxiliaries are :

• toroidal field power supply (700 kW) ;

• the cryogenic system capable of keeping the toroidal field magnet components cold (1.5 MW);

• refrigeration, which removes the heat deposited by the plasma on the materials facing it (1.6 MW).
