La presente Norma definisce e descrive le caratteristiche della tensione di alimentazione riguardanti: frequenza, ampiezza, forma d’onda, simmetria delle tensioni trifase. Queste caratteristiche sono soggette a variazioni durante il normale esercizio di un sistema di alimentazione a seguito di variazioni di carico, disturbi generati da determinate apparecchiature e del verificarsi di guasti, che sono principalmente dovuti ad eventi esterni. Le caratteristiche variano in modo aleatorio sia nel tempo, con riferimento ad uno specifico terminale di consegna, sia nella posizione, con riferimento a qualunque istante assegnato. A causa di queste variazioni ci si può aspettare il superamento dei livelli delle caratteristiche in un ridotto numero di casi. Alcuni dei fenomeni che incidono sulla tensione sono particolarmente imprevedibili, cosicché è impossibile dare valori specifici per le caratteristiche corrispondenti. I valori dati per tali fenomeni, ad esempio buchi di tensione e interruzioni, dovranno essere interpretati di conseguenza.
La presente Norma costituisce la ristampa senza modifiche, secondo il nuovo progetto di veste editoriale, della Norma pari numero ed edizione (Fascicolo 2562 E).

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.
