Issue Num.:  18036 E
Commitee: CEI-CT14
Questa Norma si applica ai trasformatori di media potenza da 25 kVA fino a 3 150 kVA con tensione massima per apparecchiature fino a 36 kV, o in reti a bassa tensione (LV) con tensione massima per apparecchiature fino a 1,1 kV dotate di dispositivi di regolazione della tensione. I trasformatori di distribuzione con regolazione della tensione sono trasformatori dotati di componenti per il controllo della tensione primaria o secondaria per la regolazione della tensione sotto carico. L'obiettivo principale dell'installazione di un VRDT è quello di regolare il livello di tensione della rete a bassa tensione (cioè 400 V) per evitare la violazione dei limiti definiti da Norme o regolamenti. Il VRDT deve funzionare correttamente come trasformatore step down e step up. I trasformatori oggetto di questa Norma sono conformi ai requisiti stabiliti dalla Norma IEC 60076 (tutte le parti) e, se non diversamente indicato in questa Norma, sono anche conformi alle Norme CEI EN 50160 e CEI EN 50588-1.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
La presente Norma recepisce il testo originale inglese della Pubblicazione IEC.

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.
