Questa Norma fornisce tutti i requisiti specifici per i trasformatori di corrente da utilizzare in applicazioni in corrente continua (DCCT), qualunque sia la tecnologia utilizzata. Il segnale di uscita può essere analogico o digitale.
Essa si applica ai trasformatori di corrente di nuova costruzione utilizzati per applicazioni di misura, protezione e/o controllo in sistemi di alimentazione in corrente continua con una tensione nominale superiore a 1,5 kV.
La Norma si applica ai trasformatori di corrente destinati ad essere utilizzati in applicazioni in corrente continua con almeno una delle seguenti funzioni:
• misurare la corrente continua (con armoniche significative);
• resistere alla tensione continua.
A seconda della collocazione nel sistema in corrente continua, esistono diversi tipi di applicazione, che sono brevemente descritti, insieme alla forma d'onda approssimativa della tensione o della corrente.
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.
