Préface Cette norme constitue la première édition de la CSA C802.4, Guide pour la détermination de la puissance en kVA des transformateurs de type sec, de classe 1,2 kV, monophasés et triphasés. Le groupe CSA exprime sa sincère gratitude pour la contribution qu’ont apportée BC Hydro, Manitoba Hydro, Hydro Québec, l’Association canadienne de l’électricité (ACÉ), Efficiency Nova Scotia et Sask Power pour l’élaboration de la présente norme. Ce guide a été préparé par le Sous-comité sur le rendement des transformateurs de type sec, sous l’autorité du Comité technique sur les produits industriels et du Comité directeur stratégique sur le rendement, l’efficacité énergétique et les énergies renouvelables, et a été officiellement approuvé par le Comité technique. Cette norme a été élaborée conformément aux exigences du Conseil canadien des normes concernant les Normes nationales du Canada. Cette norme a été publiée en tant que Norme nationale du Canada par Groupe CSA. Domaine d'application 1.1 Le guide s'applique à tous les transformateurs de type sec de classe 1,2 kV régis par les normes CSA C22.2 No. 47 et CSA C9 pour les applications commerciales et industrielles. 1.2 Le guide n'est pas applicable aux transformateurs utilisés pour des charges spéciales tels que les transformateurs de commande, transformateurs de redresseurs, transformateurs de mise à la terre, et transformateurs de mines. 1.3 Le guide ne comprend pas le traitement des harmoniques, étant reconnu que la prévision et le traitement des harmoniques de la charge et de tension constitue en lui-même un important problème. Note: On a prévu que les harmoniques seront traitées dans une future édition. 1.4 Le guide doit être appliqué tant aux installations neuves qu'au remplacement d'installations existantes.
