IEC 60287-3-2:2012 sets out a method for the selection of a cable size taking into account the initial investments and the future costs of energy losses during the anticipated operational life of the cable. Matters such as maintenance, energy losses in forced cooling systems and time of day energy costs have not been included in this standard. Two examples of the application of the method to hypothetical supply systems are given in Annex A. La CEI 60287-3-2:2012 traite du choix economique de la section dun cable prenant en compte les couts des investissements initiaux et les couts futurs des pertes denergie pendant la duree de service attendue du cable. Les questions telles que la maintenance, les pertes denergie dans les systemes a refroidissement force et les couts horaires de lenergie ne sont pas traitees dans cette norme. Deux exemples dapplication de la methode a des systemes dalimentation theoriques sont donnes a lAnnexe A.
