This document focuses on the abstract interface between an application and the data processor and includes the specification and definition of application commands and responses. It allows data and commands to be specified in a standardised way, independent of the ISO/IEC 18000 series air interfaces. This document: —    provides guidelines on presenting data as objects; —    defines the structure…

IEC 60038:2009+A1:2021 specifies standard voltage values which are intended to serve as preferential values for the nominal voltage of electrical supply systems, and as reference values for equipment and system design. This seventh constitutes a technical revision. The significant technical changes are: - the addition of the values of 230 V (50 Hz) and 230/400 V (60 Hz) to Table 1; - the…

L'IEC 60038:2009+A1:2021 spécifie des valeurs de tension normale destinées à servir de valeurs préférentielles pour la tension nominale des réseaux d'alimentation électrique, et de valeurs de référence pour la conception des matériels et des réseaux. Cette septième édition constitue une révision technique. Les modifications techniques majeures sont: - une clarification du domaine d…

IEC 61970-456:2021 belongs to the IEC 61970-450 to IEC 61970-499 series that, taken as a whole, defines at an abstract level the content and exchange mechanisms used for data transmitted between power system analyses applications, control centres and/or control centre components. The purpose of this document is to rigorously define the subset of classes, class attributes, and roles from the CIM…
