  • Compartment - Canadian Nuclear Safety Commission

To handle the various needs, a hierarchy of four classes of power has been developed based on the urgency or importance of maintaining power to individual loads. Each class has both a normal power source and an emergency power source. The emergency power source takes over when the normal source is not available.


  • Alimentation (Distribution électrique)
  • Centrales nucléaires
  • Tiroir - Commission canadienne de sûreté nucléaire

Pour gérer ces différents besoins, on a classé les charges en quatre catégories d'alimentation, selon l'urgence ou l'importance de les alimenter. On a assigné à chaque catégorie une source d'énergie normale et une source de relève (auxiliaire). Cette dernière est activée lorsque la source normale d'énergie ne peut assurer l'alimentation.
