IEC 61970-301:2020 lays down the common information model (CIM), which is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of network applications…

IEC 61970-301:2020 Le modèle d'information commun (CIM – common information model) est un modèle abstrait qui représente tous les objets principaux d'une entreprise de service public d'électricité habituellement nécessaires aux opérations d'une entreprise de service public d'électricité. La représentation normalisée des ressources de systèmes de puissance comme classes et…

IEC 60263:2020 specifies standard aspect ratios for logarithmic or level characteristics expressed in decibels versus a logarithmic frequency axis and ranges for the radius of polar diagrams of level. Applications include hard copy printouts, electronic files (e.g., PDF files), scientific publications, screen displays in computer programs and apps, as well as graphs in standards. Informative…

L'IEC 60263:2020 spécifie les formats normalisés des caractéristiques logarithmiques ou de niveau exprimées en décibels en fonction d'un axe de fréquence logarithmique et des domaines de variation du rayon des diagrammes polaires de niveau. Les applications incluent les copies papier, les fichiers électroniques (fichiers PDF, par exemple), les publications scientifiques, les affichages…

IEC 61753-1:2018+A1:2020 provides guidance for the drafting of performance standards for all passive fibre optic products. This document defines the tests and severities which form the performance categories or general operating service environments and identifies those tests which are considered to be product specific. Test and severity details are given in Annex A. This second edition cancels…
