Essais en court-circuits UJ56 et RR57

Bonjour,

Les visites des installations électriques des ouvrages cités en objet ont été réalisées à ce jour. Aucune non conformité ne s'oppose à ce que les essais en court-circuit soient effectués à partir du 20 novembre 2006. Les rapports de visite parviendront ultérieurement aux responsables de chaque installation.

Cordialement,
