La Norma specifica il modello informativo degli apparati e delle funzioni relativo all'uso comune delle applicazioni per l'automazione nell'ambito di sistemi elettrici. Inoltre essa contiene il modello informativo degli apparati relativo alle applicazioni nelle sottostazioni elettriche.
Più in particolare la norma definisce i nomi dei nodi logici compatibili e degli "oggetti-dati" inclusivi della loro relazione, ai fini della comunicazione tra i dispositivi elettronici intelligenti (IED).
I principali cambiamenti rispetto alla precedente edizione riguardano sia alcune correzioni e chiarimenti emersi dal confronto con la comunità degli utilizzatori sia l'estensione a nuovi nodi logici correlati ai domini della qualità dell'energia elettrica e dei modelli di dati statistici e storici nonché a quanto specificato dalle Norme IEC 61850-90-1, IEC 62271, EN/IEC 61850-7-410 e EN/IEC 61850-7-420.
La Norma in oggetto sostituisce completamente la Norma CEI EN 61850-7-4:2004-11, che rimane applicabile fino al 01-06-2013.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.

ICS

International Classification for Standards (ICS) is an international classification system for technical standards.

The ICS is a hierarchical classification organized on three levels.

Level 1 covers the main fields of activity in standardization, e.g. road vehicle engineering, agriculture, metallurgy.

Each field has a two-digit notation, e.g.

  43    Road Vehicle Engineering

The main fields are subdivided into groups (level 2). The notation of a group consists of the field notation and a three-digit group number, separated by a point, e.g.

  43.040    Road vehicle systems

Some groups are further divided into sub-groups (level 3). The notation of a sub-group consists of the group notation and a two-digit number, separated by a point, e.g.

  43.040.20 Lighting, signaling and warning devices

You can identify the ICS code of your interest by typing the code or a keywordword in the dropdown ICS field, and by selecting one of the filtered results.

Search also in the summary/description of the standard

By flagging this control, the search for keywords will not be limited to the Standard Number and Title fields, but will also be performed in the Abstract of the standard.

This way, you will get more results.

You should use this option when you can not find the desired result with the standard approach and it is necessary to extend the scope of the search: by increasing the number of results, you will increase the number of non-relevant elements, as well.
